speed while going to school from house = 16 km/hour
speed while coming back home from school = 15 km/hour
total speed = 31km /hour
time taken = 73/4 hours
distance = speed * time
= 31 km/hour *(73/4 )hours
= 2263/4 km
= 565.75 km
speed while coming back home from school = 15 km/hour
total speed = 31km /hour
time taken = 73/4 hours
distance = speed * time
= 31 km/hour *(73/4 )hours
= 2263/4 km
= 565.75 km
