Question

A tennis lesson lasts from 9:00 a.m. to 10:00 a.m., and should include an 8-min break with equal time before and after the break. At what time should the break start?

Answer 1

8:26 AM

Explanation:

9:00 a.m. to 10:00 a.m constitute one hour

1 hour = 60 minutes

as we have to distribute time within 1 hour only, it is better to take it in minutes as we have to divide it into three parts.

Given break duration = 8 minutes

let time before break and after break be x minutes.

Thus,

Time before break + interval duration+Time after break = 60 minutes

x + 8 + x = 60

=> 2x = 60-8 = 52

=> x = 52/2 = 26

Thus, first lesson should end at 26 minutes

so time will be 8 Am + 26 minutes = 8:26 AM

Thus, break will start at 8:26 AM.
