Question

Brad began working on a project at 10:15 A.M. He finished the work at 5:08 P.M.

How long did it take Brad to complete the project?

Answer 1

It is a good idea to convert the times into internation time

thus, 5:08 becomes 17 08

Substraction:

17 08 - 10 15

= 16 68 - 10 15 ( I took one hour from 17 and added 60 minutes to 08)

= 6 53

he worked 6 hr 53 mins
