5 bibes are required to fill a petrol tank in a hours 20 minuts. How long will it take for 8 pipes of the some type are used? |
|
Answer» We can SEE that if the NUMBER of pipes increases, the time decreases. So, inverse proportion is in action here. So, 5pipes=1hr 20 min=80 min[1hr=60min] 1 pipe=5×80 mins. So, 8pipes=(5×80)÷8mins=50mins So, 8 pipes will fill the tank in 50 mins. or 5/6 hr. Please mark the ANSWER as brainliest if you think this answer deserves it. |
