Mike rides his bike 30 km in 150 minutes. What is his average speed in kilometers per hour?

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h. Let's take a more complex example: what's the average speed if you covered 425.5km in 5 hours 22 minutes and 30 seconds?

Mike average speed is 5 kilometers per hour, uhh i hope so
