Question

If it takes 6 men 4 days to dig a hole 3 meters deep, how long with it take 10 men to dig a hole 7 meters deep?

round your answer to the nearest whole day

Answer 1

1) 3 : 4 = 0,75 m 6 men a day

2) 0,75 : 6 = 0,125 m 1 man a day

3) 0,125 × 10 = 1,25 m 10 men a day

4) 7 : 1,25 = 5,6 (days)

5,6 ≈ 6 days

It will take 6 days for 10 men to dig a hole 7 meters/
