For the first part of journey,
Speed=40km/h and time=15min=1/4 hour
Using ,speed=distance/time
Distance=40 x 1/4=10km
For the second part of journey,
Speed=60km/h and time=15 min=1/4 hour
Then distance=60 x 1/4=15 km
Total distance travelled in whole journey=10+15=25 km
Speed=40km/h and time=15min=1/4 hour
Using ,speed=distance/time
Distance=40 x 1/4=10km
For the second part of journey,
Speed=60km/h and time=15 min=1/4 hour
Then distance=60 x 1/4=15 km
Total distance travelled in whole journey=10+15=25 km

Speed for first 15 minutes = 40km/h Now 15 minutes= 15/60 hours Distance1 = Speed × Time = 40 × 15/60 = 10 km Speed for last 15 minutes = 60km/h Now 15 minutes= 15/60 hours Distance2 = Speed × Time = 60 × 15/60 = 25 km Now total distance covered = distance1 + distance2 = 10 km + 25 km = 35 I'm Answer) 35 km
