the average speed is given by ...
S avg = total distance travelled / total time taken
here,
total distance travelled is -
60 + 1/2*40
= 80km
and total time taken is -
1 + 1/2
= 3/2hrs
therefore,
S avg = 80/(3/2)
= 53.33 km /hr
S avg = total distance travelled / total time taken
here,
total distance travelled is -
60 + 1/2*40
= 80km
and total time taken is -
1 + 1/2
= 3/2hrs
therefore,
S avg = 80/(3/2)
= 53.33 km /hr
