Question

You have trained all year for a marathon. In your first attempt to run a marathon, you decide that you want to complete this 26-mile race in 4.5 hours.
What would your average speed have to be to complete the race in 4.5 hours? Give you answer in kilometers per hour.

Answer 1

26 miles is roughly 41.84 kilometers. So all we have to do is put 41.84 over the time.
 
41.84/4.5

9.298 km/hr
