Question

An airplane travels 645 miles in 3 hours at a constant speed. How much time will it take traveling 1,075 miles?

Answer 1

9514 1404 393

Answer:

5 hours

Explanation:

Time is proportional to distance:

t/1075 = 3/645

t = 1075(3/645) = 5

It will take 5 hours to travel 1075 miles at that rate.
