Collection

John has collected half a bucket of raspberries in 45 minutes, Eva collects the whole bucket in an hour.

How many minutes it would take to fill a bucket if the two children work together?

Result

t =  36 min

Solution:


t/(2*45)+t/60 = 1

1.666667t = 60

t = 36

Calculated by our simple equation calculator.
