Question 24563
Let x be the time.
45x+55x=240
100x=240
x=2.4
You know that the trip now took 2.4h, now to find the distance, but mulitplying each cars' speed by 2.4


45(2.4) = 108
55(2.4) = 132


Hence the car with the speed of 45mph travelled 108 miles and the car with the speed of 55mph travelled 132 miles.
