Question

A hot air balloon moves at a rate of `38` km per hour. At this rate, how long will it take to fly `190` km?

Answer 1

5 hours

Explanation:

turn the problem into an equation:
`y=38x`
`x` being the hours and we want to know how many hours we need to go until reach 190 km.
`190=38x`
solve for hours `x`
`x=190/38`
`x=5`
it will take 5 hours.
