Answer;
= 1.5 hours or 1 hour 30 minutes
Solution;
Speed is given by; distance divided by time,
Thus; speed = Distance/time
Which means time is given by; distance divided by time
That is; Time = Distance/speed
In our case; speed = 10 mph , distance= 15 miles
Time = 15/10
= 1.5 hours
Therefore, the cyclist rode at an average speed of 10 mph for 15 miles and took 1.5 hours.
