A car drives at a speed of 34 2/3 mph. How many miles will the car travel in:

40 min?

40 minutes is not a full hour so you need to convert this to hours

40 minutes / 60 minutes = 2/3 of an hour

So a car driving at the rate of 34 2/3 mph will go

34 2/3 * 2/3 = Miles in 40 minutes

40 * (4/9) = ? or

160/9 = ? or

17 7/9 Miles
