Short Answer

Expert verified

The speed of jet is 150 mph .

Step by step solution

01

Step 1. Given Information.

A private jet can fly 1,210 miles against a 25-mph headwind.

A private jet can fly 1694 miles with a 25-mph tailwind.

02

. Equations for Ratio and Proportion

Let r be the speed of the jet .

The formula for speed is as :-

Speed=DistanceTimeTime=DistanceSpeed

Since , Time taken is same for both the conditions.

Therefore , The proportionality equation is :-

1210r-25=1694r+25

03

. Solving the Proportional equation .

Solving the equation :-

1210r-25=1694r+251210(r+25)=1694(r-25)1210r+30250=1694r-42350-484r=-72600r=150

Therefore, The speed of jet is 150 mph.
