Question 1206959
ater is leaking fron a tank at a constant rate . At 230pm the tank is 3/5 full .At 325pm the tank was 2/7 full. At what time will the tank be empty.

from 2,30 pm to 3.25 pm  55 minutes

In 55 minutes tank drained = 3/5 -2/7  Take LCM

= 21/35 - 10/35  = 11/35

11/35 of the tank drained in 55 minutes

1 tank draining will take (35/11)*55=175 minutes

175 minutes = 2 hours 55 minutes

you can find the actual time by adding this time
