Question

A baker decorates $42$ cupcakes in $30\text{minutes}$. She decorates cupcakes at a constant rate. How many cupcakes can the baker decorate per minute?

Answer 1

Determining the number of cupcakes decorated per minute:

Number of cupcakes decorated$=42$

Time $=30\text{minutes}$

$\text{∴Cupcakes per minute}=\frac{\text{Number of cupcakes}}{\mathrm{Time}}$

Substituting the values we have,

Cupcakes decorated per minute$=\frac{42}{30}$

$=1.4$

Therefore, the number of cupcakes that the baker can decorate per minute is $1.4$.
