Step-by-step explanation:
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes = 60/15hour
Distance covered = 240× 60/15
=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60× 60
15
=15km
∴ Total distance covered = (10+15)km = 25 km
∴ 25

case 1
S=20KM/hr
T=15MIN
1/60*15=3/12=1/4hr
D=SxT
=20x1/4=5KM
case 2
S=60KM/hr
T=15MIN
1/60*15=3/12=1/4hr
D=SxT
=60x1/4=15KM
TOTAL DISTANCE=case1+2
=5+15=20 KM
