Solution
The correct option is C 4
Volume of the glass = 240 mL
Time taken to empty the glass
= 2 hours
= 2 × 60
= 120 minutes
Water wasted in a minute = 240 ÷ 120
= 2 mL
Volume of the glass = 240 mL
Time taken to empty the glass
= 2 hours
= 2 × 60
= 120 minutes
Water wasted in a minute = 240 ÷ 120
= 2 mL
