Question

What fraction of a clockwise revolution does the hour hand of a clock turn though, when it goes from 1 to 10?

Sum

Solution

We may observe that in 1 complete clockwise revolution, the hour hand will rotate by 360°.

When the hour hand goes from 1 to 10 clockwise, it will rotate by 3 right angles or 270º.

Fraction = `270^circ/360^circ = 3/4`
