Answer:

10 days and 16 hours.

Step-by-step explanation:

15 men work in 16 days to complete the work. So 1 man contributes 16/15 days.  

For 20 men there is an addition of 5 men. [20–15)* 16/15] days = 16/3 days. Substract 16/3 days from 16 days = 16 - (16/3) = 10 days and 16 hours.

Answer:

12

Step-by-step explanation:

Let 20 men will take x days to complete the work.

Since, there is a relation of inverse proportion between no of men and no of days.

Therefore,

20x = 16 \times 15 \\  \\ x =  \frac{240}{20}  \\  \\ x = 12

coldgirl [10]

Answer:

1 mile/hr

Step-by-step explanation:

Let the Speed of the boat still in water = a

Speed of the current = b

We know from this formula that speed = distance/time

Hence,

A canoe traveled Downstream with the current and went a distance of 15 miles in three hours.

Downstream = a + b = 15/3

a + b = 5 .........Equation 1

On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip.

Upstream = a - b = 15/5

a - b = 3 ..............Equation 2

Combining both Equation together

a + b = 5 .........Equation 1

a - b = 3 ..............Equation 2

Subtracting Equation 2 from Equation 1

2b = 2

b = 2/2

b = 1miles/hr

Since b = speed of the current which can also be called rate of the current, the rate of the current = 1 miles/hr
