A trained bulldog can run for 5 hours at a rate of 20 mph while it can run for for only 2 hours at a speed of 25 mph.the distance covered by running at the slower speed is what percent more than the distance covered by running at the faster speed?
distance at 20 mph = 5(20) = 100 miles
distance at 25 mph = 2(25) = 50 miles
