Question

a pump can fill 2400 litres an hour and its replacement model can fill 2.5% more, how man litters an hour can the new model fill​

Answer 1

Answer:

2,460 liters per hour

Step-by-Step Explanation:

The problem above requires only two operations: multiplication and addition. First, you have to answer this question: How much is 2.5% of 2,400 liters?"

You may do this by multiplying 2,400 by 2.5%.

2,400 x 2.5% (0.025) = 60 liters (this is the amount that the new model can fill more than old model).

Then, you have to add 60 liters to 2,400 liters.

2,400 liters + 60 liters = 2,460 liters

This means that the new model can fill 2,460 liters per hour.
