The number of hours required for 3 tractors to plow the field is 2.4 hours
Solution:
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
[tex]\text{ time taken for 1 tractor } = \frac{\text{ time taken for 5 tractor}}{5}[/tex]
[tex]\text{ time taken for 1 tractor } = \frac{4}{5} \text{ hours }[/tex]
So time taken for 3 tractors is given as:
time taken for 3 tractor = time taken for 1 tractor x 3
[tex]\text{ time taken for 3 tractor} = \frac{4}{5} \times 3 = \frac{12}{5}[/tex]
[tex]\rightarrow \frac{12}{5} = 2.4[/tex]
So number of hours required for 3 tractors to plow the field is 2.4 hours
