If you ride your bicycle at an average speed of 15 km/h for 2 hours, how far will you go?

Distance traveled is a function of the speed of an object and the time during which it maintained the speed. Distance is calculated as the product of speed of the object and the time duration. That is,

Distance traveled = average speed x time

In this case, the average speed of the bicycle is given as 15 km/h and the time duration is given as 2 hours. Thus, the distance traveled can be calculated as:

distance traveled by the bicycle in 2 hours = speed of bicycle x time duration

= 15 km/h x 2 h = 30 km.

Thus, the bike will travel a distance of 30 km in 2 hours, if the average speed of the bicycle is 15 km/h.

Note that if the average speed was not given, we would need to multiply speed and time for all the duration when speed was different. In that case, distance traveled would have been:

distance = `sum_(n=1)^oo` `speed_n xx time_n`

Hope this helps.
