Question

A jet takes 5 3/4 h to fly 2475 mi from new york city to los angeles. about how many hours will a jet lying at the same average rate take to fly 5452 mi from los angeles to tokyo?

Answer 1

Explanation:

A jet takes 5 3/4 hours to fly 2475 miles from New York city to los Angeles. Let us convert 5 3/4 hours to decimal, it will be 5.75 hours. So it takes the jet 5.75 hours to fly 2475 miles from New York city to los Angeles.

Distance = speed × time

Speed = Distance / time

The speed of the jet would be

2475 / 5.75 = 430.43 miles per hour

If another jet travels 5452 miles from los Angeles to Tokyo at the same average rate or speed as the former, then the number of hours that it will take to travel from los Angeles to Tokyo will be the

Distance travelled/ speed. It becomes

5452/430.43 = 12.67 hours
