Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t

10
Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t Now, plug in the given values into the formula.

11
Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t s = 10 km / 40 min.

12
Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t s = 10 km / 40 min. And solve!

13
Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t s = 10 km / 40 min. s = 0.25 km/min * 60 min. / hr =

14
Speed Calculations A cross-country runner runs 10 km in 40 minutes. What is his average speed? Given Given F Formula Work Answer d = 10 km t = 40 min s = d/t s = 10 km / 40 min. s = 0.25 km/min * 60 min. / hr = Write the answer in the answer section. Do not forget the units!
