Question

The number f of miles a helicopter is from its destination x minutes after takeoff is given by f(x)=75−1. 5x. The number f of miles a commercial jet is from its destination x minutes after takeoff is shown in the graph below

Answer 1

75 miles in 50 minutes

Explanation:

f(x) = 75 - 1.5x

f(0)= 75-1.5(0)=75

=> 75-1.5x=0

=> 1.5x =75

=> x=50
