Question

Water flows into a tank of 60m*40m at the base through a pipe whose cross-section is 2decimetres*1.5decimetre at the speed of 8km per hour. At what time will the water be 5m deep? PLS ANSWER WITH EXPLANATION

Answer 1

Answer:

50 hrs

Step-by-step explanation:

Let in x hours the water be 5m deep in the tank. Volume of water required in the tank= (60*40*5 ) m3

Volume of water flown in the tank in x hours

(2/10*1.5/10*8000*x )m3

2/10*1.5/10*8000*x )m3= 60*40*5

240x=60*40*5= x= 60*40*5/240

= 50 hours

Hence, the required time is 50 hours
