To determine

Tofind: the time taken by the Air force fighter jet.

Answer to Problem 37CCR

the time taken by jet is $\text{8 }$ hour.

Explanation of Solution

Given information:

Thespeed of jet is $650$ miles per hour and distance is $5200$ miles.

Calculation: to find the time taken by the jet first use the speed formula and then substitute and then simplify,

  $\begin{array}{l}\text{speed}=\frac{\text{distance}}{\text{time}}\\ \text{650}=\frac{\text{5200}}{\text{time}}\text{ [substitute]}\\ \text{time}=\frac{5200}{650}\text{ [cross multiplication]}\\ \text{time}=\text{8 [divide]}\end{array}$

Thus, the time taken by jet is $\text{8 }$ hour.
