Question

A man walks 10m east but runs 5m west every day. How many days will it take him to cross a building 380m east?

Answer 1

answer would be 380÷5=74

Answer 2

$\bold \red{hey \: mate}$

Distance travelled in East = 10m
Distance travelled in West = 15m
Net distance travelled in East = 15-10 = 5m

No of days required = Total distance / Net
distance
= 380 / 5
= 76 days

$<marquee> so the man will need 76 days to cover 380m$
