<h3>Answer: Choice C</h3>

Explanation:

If 5 tractors can plow a field in 4 hours, how many hours will it take 3 tractors to plow the field?

Mrac [35]

The number of hours required for 3 tractors to plow the field is 2.4 hours

<em><u>Solution:</u></em>

Given that 5 tractors can plow a field in 4 hours

We have to find out number of hours required for 3 tractors to plow the field

5 tractors can plow a field in 4 hours, So time taken for 1 tractor

$\text{ time taken for 1 tractor } = \frac{\text{ time taken for 5 tractor}}{5}$

$\text{ time taken for 1 tractor } = \frac{4}{5} \text{ hours }$

<em><u>So time taken for 3 tractors is given as:</u></em>

time taken for 3 tractor = time taken for 1 tractor x 3

$\text{ time taken for 3 tractor} = \frac{4}{5} \times 3 = \frac{12}{5}$

$\rightarrow \frac{12}{5} = 2.4$

So number of hours required for 3 tractors to plow the field is 2.4 hours
