Julian Average speed is about 11 km per hour

Speed

Speed is the ratio of total distance travelled to total time taken. It is given by:

Speed = distance / time

Let d represent the distance travelled by the simulated biker. After 15 minutes (0.25 hours):

20 = d/0.25

d = 5 km

Distance travelled by Julian = 5 - 2 1/4 = 2.75 km

Julian Average speed = 2.75 / 0.25 = 11 km per hour

Julian Average speed is about 11 km per hour
