Question

A bicycle completed the first 200 m of a ride in 38.31 s. What was the bicycle's average speed in kilometers per hour

Answer 1

The bicycle average speed in kilometers per hour is 18.9km/hr.

Step-by-step explanation:

The reading above states that a car travel a distance of 200m in a time of 38.31s and is asking for the speed in kilometers per hour (km/hr). In this case change 200m to km and 38.31s to hr

Using the conversion factor

1km = 1000m

1hr = 3600s

200m = 1km/1000m = 0.2km

38.31s = 1hr/3600s = 0.0106hr

Average speed = distance traveled/time taken

Average speed = 0.2km/0.0106hr

Average speed = 18.9km/hr

Therefore the bicycle average speed in kilometers per hour is 18.9km/hr.
