Albert raced 3 times as fast as Bernard. In fact, Albert raced 45 miles in 3 hours less than it took Bernard to race 30 miles. How fast did each of them race? What were the times of each racer?

Answer 1

albert's speed = 3 time bernard's speed, a=3b

albert raced 45 miles in 3 hours less than bernard ran 30 miles

bernard's speed = b = 5 mph

albert's speed = a = 3b = 15 mph

albert ran 45 miles in 3 hours = 3 hours less than bernard ran 30 miles

bernard ran 30 miles in 6 hours
