Question

Ivan drove 804 miles in 12 hours. At the same rate, how many miles would he drive in 9 hours?

Answer 1

804 miles/12 hours = 67 miles

Which means that Ivan drove 67 miles per hour

67 miles*9 hours = 603 miles

Which means that in 9 hours Ivan can drive 603 miles if he drives at a constant speed of 67 miles per hour.
