Question

A large aquarium of water is being filled with a hose. Due to a problem, the sensor does not start working until some time into the filling process. The sensor starts its recording at the time zero minutes. The sensor initially detects the tank has 225 liters of water in it.

The hose fills the aquarium at a constant rate of 15 liters per minute. What will the sensor read at the time of 5 minutes?

Answer 1

300

Explanation:

225 is what you start with. 15 liter per min means in 5 min it will be 75 because 5x15=75, then 75+225=300
