Question

kali trains for a race by running round a track. each lap is 400 meters. she run 4 kilometers each day. how many lapsaround he track does kali run in 3 days

Answer 1

1 km = 1000m
so 4 km = 4(1000) = 4000 m

so Kali runs 4000 m per day
4000/400 = 10 laps per day

for 3 days = 3(10) = 30 laps for 3 days
