Question

Quantity-I: Pipe P fills an empty tank in 25 hours, while pipe Q fills it in 40 hours. If the tank is initially 36% full, pipe P operates for 6 hours before being shut off. Determine how much time pipe Q will take to fill the rest of the tank. Quantity-II: Determine the time a bus will take to cover a distance of 1080 km, given its constant speed is 20 m/s.
