Question

An air plane can cruise at 640mph. How far can it fly in 3/2 Ths of an hour?

Answer 1

Answer: 960 miles

3/2 of an hour would be 1 hour and 30 min or an hour and a half

640mph (mph = miles per hour)

1/2 of an hour is 30 minutes so its 640 miles in half so 320

now all you gotta do is add it

so 640 + 320 = 960
