Question

Train A got from one city to another 45min faster than train B. Train's A speed is 48km/h, train's B speed is 36km/h. What is the distance between the cities?

Answer 1

I am just writing to clarify what the last contributor had to say.

Explanation:

In this problem, we should work with the formula `S = d/t`, where s is speed, d is distance, and t is time.

We can rearrange the formula to `S xx t = d`. Assuming the time it takes train A is x (hours).

`48 xx x = 36 xx (x + 3/4)`

`48x = 36x + 27`

`12x = 27`

`x = 9/4`

So, it takes train A `9/4` hours to travel between the two cities.

Therefore, we can plug in our values into the equation to solve for d: `48 = d/(9/4)`

`108 = d`

Thus, the distance between the two cities is of 108 kilometres.

Hopefully this helps!
