Question

Ebony lifts weights 3/4 hours a day 5 days a week .How many hours does Adam lifts weights 1/2 as long 2 days a week and twice as long as 3 days a week .How many hours does Adam lifts weights each week?

Answer 1

Answer:

Ebony -3/4hrs per day

= 3/4 × 24(divided both side by 4)

=(3×6)hrs

= 18hrs per day

1 day = 18hrs

5 days = ( 5×18)hrs

= 90hrs in 5days

Adam - 1/2 hrs per day

=(1/2 × 24) hrs

= 12 hrs per day

1 day = 12 hrs

2days = ( 2×12) hrs

= 24hrs per 2days

let twice be 2x

12 hrs = 1day

12(2x)= 24hrs

24x=24( divided both sides by 24)

x= 1hrs

:. 1day =1 hr

3 days =(3×1) hrs

=3hrs
