(a) Amount of water that flowed out = 160l - 20l = 140l
Average amount of water that flowed out per minute = 140l / 50 min = 2.8l
(b) 4/5 of tank = 160l
5/5 of tank = 160l / 4 x 5 = 200l
Amount of water left = 20l
Fraction of water left = 20l / 200l
= 1/10
Average amount of water that flowed out per minute = 140l / 50 min = 2.8l
(b) 4/5 of tank = 160l
5/5 of tank = 160l / 4 x 5 = 200l
Amount of water left = 20l
Fraction of water left = 20l / 200l
= 1/10
