Patrick Simpson - 02.02.2016 16:18Since you know how many miles Mr Mackenzie drives in 2 hours, just simply divide 120 by 2 to get how many miles he drives in one hour. 120 ÷ 2 = 60 Now you can multiply 60 by 5 (for the 5 hours) to see how far he drives in that time frame. 60 × 5 = 300 So, basically, for each hour you add 30 miles.
