0.33hours
Step-by-step explanation:
The speed of a moving body can be calculated by using the formula;
Speed = distance รท time
According to the information provided, the time it would take Craig to ride the skateboard on the sidewalk at an average speed of 18km/h for a distance of 6km is being asked.
Hence, derived from the above formula;
Time = Distance/speed
Time = 6/18
Time (hr) = 0.3333hr or 19.8minutes
