A car traveling at a constant speed goes 150km in 7200s. what is the speed of the car?

Use this formula: distance = rate x time

so, distance=150km time = 7200 seconds which equals 2 hr rate = unknown

150 = rate x 2 or 150 = 2r

Now, rate = 150 divide by 2; therefore rate = 75 km/hr

the answer is the car travels 75 km per hr
