Problema Solution
mike and adam left a bus terminal at the same time and traveled in opposite directions. Mike's bus was in heavy traffic and had to travel 20 mi/h slower then Adam's bus. after 3 hours, their buses were 270 miles apart. how fast was each bus going?
Answer provided by our tutors
let 'v' represent the speed of Mike's bus, then 'v+20' represents the speed of Adam's bus
distance = speed * time
time = distance/speed
3=270/(v+v+20)
solving for 'v' we have v=35
35+20=55
Mike's bus travelled at 35mph, Adam's bus travelled at 55mph
