Here, it takes 3 minutes 30 seconds for a squirrel to gather 21 acorns.

Since 1 minute = 60 seconds

3 minutes 30 seconds = 3½ minutes = 3.5 minutes

To find how many acorns the squirrel will gather after 10 minutes, we have:

3.5 minutes = 21 acorns

10 minutes = x acorns

Cross multiply:


\begin{gathered} 3.5x\text{ = 21 }\ast\text{ 10} \\ \\ x\text{ = }(21\ast10)/(3.5) \\ \\ x\text{ = }(210)/(3.5) \\ \\ x\text{ = }60\text{ acorns} \end{gathered}

Therefore, after 10 minutes the squirrel will gather 60 acorns

ANSWER:

60
