Question

Terry drove 300 miles in 5 hours at a constant speed.How long would it take him to drive 420 miles at the same speed? Please help

Answer 1

divide 300 by 5 to get his average speed

300/5 = 60 miles per hour

now divide 420 by 60 to get the time

420/60 =7 hours

it will take him 7 hours to drive 420 miles
