An object moves in a straight line at #30 (km)/(hr)# for 5 minutes. What will be the distance it has travelled at the end of this motion?

Since 5 minutes is #1/12# of an hour, the distance is #d=(30(km)/(hr))xx(1/12hr) = 2.5 km#

Explanation:

By definition

#velocity=(displacement)/(time)#

So, displacement (which is the same as distance in this situation of straight line motion) is

#displacement=velocityxxtime#
