MULTIPLE SELECT QUESTION

A gear rotates 8 times every 15 seconds. Based on this information, put a check mark next to any true statement below.

The gear rotates 48 times in 90 seconds.

The gear rotates 32 times in one minute.

The gear rotates 16 times in 30 seconds.

The gear rotates 24 times in 60 seconds.

Answer explanation

The gear rotates 8 times every 15 seconds. So, in one minute (60 seconds), it would rotate 32 times (8*4). Therefore, the statement 'The gear rotates 32 times in one minute' is true. The other statements do not correctly represent the gear's rotation speed.
