Explanation:
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes =
60
15
hour
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 km is correct

total distance traveled upon total time
let X be the distance between a and b
X/t1=30
t1=X/30
t2=X/60
now
total time=t1+t2=3x/60
total distance traveled=2x
I guss you'll divide
you'll get 40
now convert the units
40×5/18
