a car travels a 20 km/hr faster than a truckl.the car covers 350 km in two hours.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?
*note: solution is a bit hard to type :) and if you cant understand since the sol. is really blur, i just used the formula distance = speed times time then a little substitution.
