Five tractors

Five tractors plow the field in 4.8 hours. How long would it take to plow this field if, after 1.5 hours of work, two tractors went to a different field?

Correct answer:

x =  7 h

Step-by-step explanation:

4.851.55+4.85(x1.5)3=1

1.5·5/(4.8·5) + (x-1.5)·3/(4.8·5)=1

0.125x = 0.875


x = 0.875/0.125 = 7

x = 7
