Answer 1

Frank worked for 68 hours in 4 weeks.

Explanation:

Given:-

Working hours of Frank on first 4 working days = 8 hours.

Working hour of Frank on fifth day = 9 hours.

To find:- Working hours for 4 weeks= ?

Solution:-

Working hours for 1 week = working hour on first 4 days of week + working hours on fifth day of week

Working hours for 1 week = 8+9

Working hours for 1 week = 17 hours per week. -----------(1)

Now,

Working hours for 4 week = 4
`*` working hours for 1 week

Working hours for 4 week =
`4* 17` ----------(from 1)

Working hours for 4 week = 68 hours.

Therefore Frank worked for 68 hours in 4 weeks.

Answer 2

Total number of hour worked by Frank is 164 hours .

Explanation:

Given as :

The number of hours worked by Frank on the first four days = 8 hours

So, Total number of hour worked by Frank on 4 days = 8 hours × 4 = 32 hours

The number of hours worked by Frank on the fifth day = 9 hours

So, Total number of hour worked by Frank in one week = total 4 day work + 5th day work

I.e Total number of hour worked by Frank in one week = 32 hours + 9 hours

Or, Total number of hour worked by Frank in one week = 41 hours

Again

Total number of weeks the Frank worked = 4 weeks

So, Total number of hour worked by Frank in all 4 week = 41 hours × 4

i.e Total number of hour worked by Frank in all 4 week = 164 hours

Hence,Total number of hour worked by Frank is 164 hours . Answer
