Presentation: Porblems of transport in our city

How many times do you need to go to work ( maybe you meant , how many days a week do you work )? If you live here then probably a lot because in our hometown there isn't too much variety, we only have one bus line and the frequency isn't enough, so it takes a long time to get anywhere. Installing new ways of transport is the best way to make life easier for the people who live here 

As I said before, we only have one bus line. We don't have a train or a subway/metro, so going anywhere is quite difficult and slow. Maybe we are just not enough people living here to justify constructing a metro or train station, that's true, but at least we need some more bus lines  in order to get to  the other cities. 

If having only one bus line wasn't enough, the frecuency is also really bad. The bus passes only once an hour, so if you miss it, you don't have any other option to get where you need to go, unless you have a car. And this implies that you have to accomodate your schedule according to the bus schedule, so probably you'll have to take the bus 2 hours beforehand and keep waiting there until the hour comes.

Finally, I'll talk about how long it takes to get anywhere. Our bus line passes through all the cities in the south of Madrid, and this means that you need at least one hour and a half to go to the Madrid city center, and that's if you're lucky and there isn't too much traffic.

In conclusion, going to work or to school can be a nightmare for those who live here, and that's why our hometown needs more public transport. There are many of us who need go to other places for work or study, and with the system we already have we need to start off  our day really early, withstand a lot of traffic and waste much of our time commuting.

How many times do you need to go to work? If you live in my city, the answer would probably be "a lot" because we have only one line of buses and the frecuency isn't enough. So it takes you long to go anywhere. Installation of new means of transport is the best way to make easier the life of the citizens easier. 

As I said before, we only have one line of buses. We don't have any trains or metro, so going anywhere is quite difficult and slow. Maybe we there aren't enough that many people living here to build a metro or train station, that's true, but at least we need more bus lines to get to other cities better communicated.

If have only one line of bus wasn't enough, the frecuency is also really bad. The bus pass just once every hour, so if you lose it, you don't have another option to go wherever you need, unless you have a car. And this implies that you have to accomodate your schedule according to the bus schedule, so probably you'll have to take the bus 2 hours before and wait there until the hour come.

Finally, I'll talk about how long take to go anywhere. Our bus line pass through all the cities in the south of Madrid, and this means that you need at least one hour and a half to go to Madrid city center, and that if you're lucky and there isn't too much traffic.

In conclusion, go to work or school is a nightmare for who is living here, and that's why our hometown needs more public trnasport. We are many who need go to other places to work or study, and with the system we already have we need to set off really early, bear a lot of traffic and waste much of our time travelling.

It's a little longer than I felt like correcting, but I corrected the first paragraph for you.

How much time do you need to get to work? (I would actually say "How much time does it take to get to work?") If you live here, probably a lot because in my hometown there isn't too much variety. We only have one line for busses and the frequency isn't high enough (sounds a little awkward, but technically makes sense), so it takes a while (or you could say "it takes a long time") to go anywhere. Installing new means of transport is the best way to make life easier here.

The first sentence confused the other two people who corrected it because you used the word "many" which implies a discrete value whereas "much" is used for quantities that don't have a precise amount.
For example: How MANY jars are there and how MUCH sand is in each jar.

To say "How many times" in this context would mean "how many separate instances did you..." rather than "for what duration of time".
