Answer:
Number of cakes decorated = 1.4 in a minute
Explanation:
A baker decorates 42 cupcakes in 30 minutes. If she decorates cupcakes at the constant rate then we have to find the number of cakes the baker can decorate in 1 minute.
We should always use the unitary method to calculate the outcome.
∵ A baker can decorate in 30 minutes = 42 cakes
∴ baker can decorate in 1 minute =
cupcakes.
Therefore, 1.4 cakes per minute will be the answer.
