Question

If the train from Milan, Italy, to Rome, Italy, takes 6 hours at a speed of 130 miles per hour, how many miles from Milan is Rome?

Answer 1

Explanation:

the speed is 130 miles / hour.

that means the train travels 130 miles in 1 hour.

so, the question is, how far is it traveling. when it is going with that speed for 6 hours ?

well, 130 × 6 = 780 miles.

formally, speed is "distance / time".

multiplying this by some time, we have then an expression of "(distance / time) × time", which is then simply "distance".
