Calvin is painting an area that is 115 square feet. He is able to paint 2.5 square feet every 2 minutes. At this rate , how long

Verdich [7]

Answer:

Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.

Step-by-step explanation:

First of all we know that the total surface are that Calvin is painting is 115 square feet.

The rate at which Calvin is painting refers to the surface area he covers every 2 minutes. This is 2.5 square feet every 2 minutes.

we can set up a relation to solve this problem

If Calvin paints $2.5 ft^{2}$ in 2 minutes

He will paint $115 ft^{2}$ in $x$ minutes

By cross multiplying, we have $x= \frac{2 \times 115}{2.5}=92 minutes$

Hence Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.
