Question

Seetha rides her bicycle to school. In morning
while going to school she average a speed of
15 km/h. On he return from
school at evening along the same route, she
averages a speed of 12 km/h. Calculate the
average speed of seetha's trip​

Answer 1

since distance covered is same in the both cases therefore we can apply the formula

Vavg=2*V1*V2/V1+V2

=2*15*12/15+12

=13.33 km/hr

hope this helps
