If 10 men can construct a 75 km long road in 5 days. How many days will be needed for 15 men to construct a 45 km long road?
Answer: 2 days
Explanation
First, let's find the work rate of 10 men:
10 men construct 75 km in 5 days, so:
Work rate = 75 km / 5 days = 15 km/day for 10 men
Now, let's find the work rate for 15 men:
Work rate for 15 men = (15/10) × 15 km/day = 22.5 km/day
Now, let's find the time needed for 15 men to construct 45 km:
Time = Distance / Work rate
= 45 km / 22.5 km/day
= 2 days
