Question

An office opens at 9:30a.m and closes at 5:30p.m with a lunch interval of 30 minutes.what is the ratio of lunch inerval to the total period in the office?

Answer 1

Lunch interval = 30 mins

Office hours:

9.30 am to 5.30 am = 8 hours = 8 x 60 = 480 mins

Time in the office:

Time in office = 480 mins - 30 mins = 450 mins

Find the ratio of lunch interval : Total Period in office

Lunch : In office = 30 : 450

Simplify by dividing by 30:

Lunch : In office = 1 : 15

Answer: 1 : 15

Answer 2

hey!

here is answer
given-



lunch interval= 30 min

office hour

= 9:30 am to 5:30 pm

= 8 hours

lets convert it into minutes

hence

8*60

480min

total time in office 480-30

450 min

ratio of lunch interval. to the total time in office

= 30:450

lets do it in fraction

30/450

3/45

1/15 when divided by 3

hence ratio is. 1:15

hope it helps

thanks
