Asked by Sylvia

A car travels 20 kph faster than a truck. The car covers 350 km in two hours less than the time it takes the truck to travel the same distance. What is the speed of the car? How about the truck?
Answered by Steve
If the truck has speed x, then the car has speed x+20

since time = distance/speed,

350/(x+20) = 350/x - 2

Now just solve for x, and figure x+20

But the x would be zero! Help!!
