To build a school;
20 workers -> 18 days.
So 1 worker -> 18/20 days.
So; 12 workers -> (12×18)/20 days.
-> (12×9)/10 days
->10.8 days.
so 10.8 days is your answer.
Hope it helps...

-- Driving at 30 mph for 20 minutes (1/3 hour), you cover 10 miles.
-- Walking at 3 mph for 10 minutes (1/6 hour), you cover 0.5 mile.
-- Average speed = (total distance covered) / (time to cover the distance)
= (10.5 miles) / ( 1/2 hour)
= 21 miles per hour.
It’s negative by the looks of it.
If you solve it you get -2.5
I hope it’s correct!
