Answer:
Given:
No. of trips through the same path = 2
The speed on the way = 40 km/h
The speed the way back = 60 km/h
To Find:
Average speed
Solution:
Avg. speed =
[tex]\frac{sum \ of \ given \ speeds}{no. \ of \ speeds \ given} \\= \frac{40+60}{2} \\= \frac{100}{2} \\= kmh^{-1}[/tex]
Hope this helps.
Thanks.
route is of trip Fromm Homme to schhool and school to home
while drving to school =40km/h
while returning speed =60km per hour
L1/40km/h
L2/60km /h
=L1/40,L2/60
t1 first trip
t2 returning trip
T1=L/40
T2=L/60
Total average speed of bus is = 2l/T1+T2
2L= L/40,L/60
2L=1/40and 1/60
2*40*60/100=48m per sec
multiply all and divide by hundread
share and thankyou for your doubt
