Question

A circular wheel makes 42 complete turns each minute.

How many degrees does it turn through in one second?

Answer 1

252

Explanation:

in each minute, the wheel makes 42 turns. That means it turns 42×360=15120 degrees in one minute (60 seconds). We want to find how many degrees it will turn in one second, not one minute, so we will divide the total degrees by 60.

15120÷60=252

So our answer is 252.
