Question

An airplane can cruise at 640 mph how far can it take in 3/5 of an hour

Answer 1

Given:

An airplane can cruise at 640 mph.

To find the distance that can be covered in 3/5 of an hour:

In 3/5 of an hour, the distance would be,

`\begin{gathered} 1\text{ hour=640 miles} \\ (3)/(5)\text{hour}=640*(3)/(5) \\ =128*3 \\ =384\text{ miles} \end{gathered}`

Hence, the distance that can be covered in 3/5 of an hour is 384 miles.
