Question

One student can paint a wall in 10 minutes. if his friend tito helps him they can finish in 5.76 mins. how long would it take tito to do it alone?

Answer 1

The answer is t = 13.71 minutes. Please Check the explanation below to remember the easy steps.

Explanation:

Let's denote the rate at which the first student paints as 1/10 walls per minute, and the rate at which Tito paints as 1/t walls per minute, where t is the time it would take Tito to paint the wall alone.

When they work together, their rates add up, so we have:

1/10 + 1/t = 1/5.76

We can solve this equation for t:

First, subtract 1/10 from both sides:

1/t = 1/5.76 - 1/10

Then, take the reciprocal of both sides:

t = 1 / 1/5.76 - 1/10

Solving this equation gives us the time it would take Tito to paint the wall alone.

So, the final answer is t = 13.71 Minutes.
