It takes 10 road workers 5 days to complete a road repair when working 2 hours a day. Working at the same pace, how many days will it take 2 people working 5 hours a day to finish it?

10 days

Step-by-step explanation:

(10×5×2) = (2×5×x)

x = 10

10 days

Step-by-step explanation:

It takes 10 road workers 5 days to complete a road repair when working 2 hours per day.

It takes 10 workers 5 days when working 2 hours per day to complete the road.

At the same pace 2 people working 5 hours a day will use ? days.

Firstly, let's calculate for 2 worker at 2 hrs per day

10 workers = 5 days at 2 hr per day

2 workers  =  ?

20/5 = 4 days at 2 hrs per day

For  2 workers at 5 hrs per day

4 days at 2 hrs per day

? days  at 5 hrs per day

cross multiply

(5 × 4)/2

20/2

10 days

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
