To be physically fit,your mother tells you to wake up early in the morning and do brisk walking.She suggest walking for 15 minutes daily for the first week.Each week ,thereafter ,she suggests that you increase the time by 5 minutes per day. On what week will it be before you are up to walking 1 hour per day?

solution:

for the first week he only walked 15 mins

and the next week his mom says to increase 5 mins daily

so we should increase 5 mins daily

so 5 × 7 days = 35 mins a week

now he walks 50 mins on second weeks end

third week = 35 mins

now he walks 85 mins third weeks end

now we got a full hour walk in third week

hence third week is the answer .
