2 cars leave down at the same time one travel West at 56 miles per hour and the other travel South at 42 miles per hour after 1 hour how far apart are the cars
distance = speed * time. So, you want
√(56^2 + 42^2)
or, if you recognize this as just a 3-4-5 right triangle scaled up by 14, the 14*5 = 70
