speed v1= 40 km/h
". V2=60km/h
let the total distance covered is x km
distance covered in S1= x/2
". ". ". S2=x/2
time taken=t1
time taken=t2
total time taken by the bus
t1=x/2/40=x/80h and t2=x/2/60=120h
Average speed.
s1+s2/t1+t2= x/2+x/2/x/80+x 120
Vav = 1/2+1/2/1/80+1/120= 80×120/120+80=48km/h
Average speed of bus age 48
