Question

In the morning a farm worker packed $3$ pints of strawberries every $4\mathrm{minutes}$, in the afternoon she packed $2$ pints of strawberries every $3\mathrm{minutes}$. What was the difference between her morning and afternoon packing rates, in pints per $\mathrm{hour}$?

Answer 1

Step-1: Finding the morning packing rate in pints per $\mathrm{hour}$:

Number of strawberries pints packed by worker in every $4\mathrm{minutes}=3$

So, number of strawberries pints packed by her in every $60\mathrm{minutes}=3\times \frac{60}{4}$

$=45$

Thus her morning packing rates in pints per $\mathrm{hour}$ is $45$.

Step-2: Finding the afternoon packing rate in pints per $\mathrm{hour}$:

Number of strawberries pints packed by worker in every $3\mathrm{minutes}=2$

So, number of strawberries pints packed by her in every $60\mathrm{minutes}=2\times \frac{60}{3}$

$=40$

Thus her afternoon packing rates in pints per $\mathrm{hour}$ is $40$.

Step-3: Find the difference between both packing rates:

The difference between both the rates $=$Morning rates $-$ Afternoon rates

$=45-40$

$=5$

Hence, the required difference between both the packing rates is $5$ pints per $\mathrm{hour}$.
