Elenna [48]

Answer:

The expression for rate per hour is $\frac{340}{45}\times 60$ .

Explanation:

Given:

A machine paints 340 toy boats in 45 minutes.

To Find:

Expression equals the rate per hour?

Solution:

Finding the expression for rate per minute:

$\text{{The rate per minute expression}} =\frac{\text{{ (number of toys painted in time given)}}}{\text{{(number of minutes taken)}}}$

So, rate per minute expression is $\frac{(340 toys)}{(45 minutes)}$ = $\frac{340}{45}$

Then, rate per hour expression $\text{{rate per minute}}\times 60 minutes$

So, rate per hour expression is $\frac{340}{45}\times60 minutes$ = 453.334 toys per hour.

Hence, the expression for rate per hour is $\frac{340}{45}\times 60$
