Answer:
The two friends will be 150 miles apart in 2 hours
Step-by-step explanation:
The two friends left the school at the same time and drove in opposite directions. One of them have a speed of 40 miles per hour while the other have a speed of 35 miles per hour .
The both of them are moving apart at the rate = 40 + 35 = 75 miles per hour
let
t = time at which they are 150 miles apart
speed = distance/time
time = distance/speed
time = 150/75
time = 2 hours
The two friends will be 150 miles apart in 2 hours
