speed=40km/hr
time=15 mins = 0.25 hrs
Therefore distance=speed×time
40×0.25=10 km
Now,
speed =60km/hr
time=15 mins = 0.25 hrs
therefore distance=s×t
60×0.25=15 km
Hence, total distance travelled = 10+15=25 km
time=15 mins = 0.25 hrs
Therefore distance=speed×time
40×0.25=10 km
Now,
speed =60km/hr
time=15 mins = 0.25 hrs
therefore distance=s×t
60×0.25=15 km
Hence, total distance travelled = 10+15=25 km

Speed for 1st 15 min= 40km/hr
Time= 15min
Distance covered(d1)=Speed×time
=40×(15/60)
=40×(1/4)
=10km
Speed for next 15 min=60km/he
Time= 15min
Distance covered(d2)= speed×time
=60×(15/60)
=60×(1/4)
=15km
Total distance travelled= d1+d2
=10km+15km
=25km
