S. S pipes can fill a tank in 80 minutes. How long will it take to all the tank if 8 pipes are​

Answer 1

(4) Distance = 360 km

Time = 4 hours

Speed = Distace / time

= 360 / 4

= 90 km/hr

So, the car should have a speed of 90 km/hr to travel a distance of 360 km in 4 hours.

(5) P1T1 = P2T2

5 x 80 = 8 x T2

T2 = (5x80)/8

T2 = 50 min (Ans)
