When Fritz drives to work his trip takes 48 minutes, but when he takes the train it takes 40 minutes. Find the distance Fritz travels to work if the train travels an average of 6 miles per hour faster then his driving.
**
let x=speed of auto
x+6=speed of auto
distance=travel time*speed (assume same for both auto and train)
(48/60)x=40/60)(x+6)
48x=40x+240
8x=240
x=30 mph
Distance=(48/60)*30=24 mi
ans:
Distance Fritz travels to work=24 mi
