Answer:
Time = 60/40
=3/2 hrTime
Distance = speed × time
= 12 × 3/2
= 18 km
Time taken to reach school when she cycles at a speed of 30 km/hr = Distance by time
=18 / 30
=3/5 hr
3/5 hr = 60 × 3/5 = 36 min

Answer:
Step-by-step explanation:
distance = speed * time
40 minutes into hour = (40/60)
distance travelled by Romani = 12*(40/60)=8km
time taken to travel by cycle = 8/30
=4/15 hr=16min
