Question

hoblos · Answer

4km/60min
in 54min  sparrow flies 4*54/60 = 3.6km
3.6km is the distance covered for going and coming back
so his friend live 1.8km away

anonymous · Answer

distance travelled in 60 min = 4000 m
distance travelled in 1 min = 4000m/60
distance travelled in 54 min = (4000 * 54)/60
distance travlled one way = (4000 * 54)/60*2 = 1800 m = 1.8 km
