of vegetables in 30 minutes.

prepare
the same amount?
(1 d.p.)

2) 6 tractors take 8 days to collect the harvest.
How long would it take 12 tractors to do the same work?
(1 d.p)

Answer 1

Explanation:

1) Inverse proportion. More assistants less time

`Time taken = (30*2)/(15)= 2*2 = 4 \ minutes`

2) More tractors less days

`Number \ of \ days = (8*6)/(12)= 4 \ days`
