Harvesters

The first harvester will harvest the grain from the field in 20 hours, and the second, the more powerful in 10 hours. How long will it take to harvest this field by both harvesters if the second harvester has to be set up first, which takes 2 hours? The first harvester then worked alone for two hours, then together.

Correct answer:

t =  8 h

Step-by-step explanation:


t/20 + (t-2)/10 = 1

3t = 24


t = 24/3 = 8

t = 8
