A train that travels 30 miles in 1/3 hour at a constant speed is going faster than a train that travels 20 miles in 1/2 hour at a constant speed. Explain or show why.

Answer 1

Calculate each rate by dividing the distance traveled by the amount of time it takes to cover that distance:

30 / (1/3) = 90 mph

20 / (1/2) = 40 mph

The train going 30 miles in 1/3 hour is going faster than the other train.
