Question 770358: a truck can travel 70 miles in the same time that it takes a car to travel 110 miles. if the trucks rate is 20 miles per hour slower than the car's, find the average rate for each Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! Let t = speed of the truck
Let c = speed of the car
c/t = 110/70
c = t+20
Then
(t+20)=(11/7)t
(-4/7)t = -20
t = 35 and c = 55
Answer: speed of the car is 55 mph and speed of the truck is 35 mph
