If 6 pipes fill a tank in 120 minutes, then 5 pipes can fill it in how many minutes​
Marianna [84]

Answer:

<u>It'll</u><u> </u><u>take</u><u> </u><u>1</u><u>4</u><u>4</u><u> </u><u>minutes</u><u> </u><u>for</u><u> </u><u>5</u><u> </u><u>pipes</u><u>.</u>

Step-by-step explanation:

{ \sf{6 \: pipes = 120 \: mins}} \\ { \sf{5 \: pipes = ( \frac{6}{5}  \times 120) \: mins}} \\  \\  = { \sf{144 \: mins}}

but practically, it seems to be abnormal. if 6 pipes take 120 mins, 5 pipes must takes a time greater than 120 mins cause amount of water flowing to the tank is decreasing.

a^2 + b^2 = c^2

18^2 + 23^2 = 30^2
