The distance traversed by a car traveling at a constant speed is directly proportional to the time spent traveling. If the car goes 90 kilometers in 9 hours, how far will it go in 5 hours? Do not use units in your answer.
50. I am not a robot.
We need to find the proportionality constant, k. So we have...
D = kT where D is the distance and T is the time
90 = K9 divide both sides by 9
10 = k
So...in 5 hours, we have
D = 10*5 = 50 (kilometers)
