What is the angle made by minutes hand in a minute?

1.	What is the angle made by minutes hand in a minute?
Answer» We know angle made by minutes hand in 15 m = 90° Let angle made by minutes hand in 1 m = x° Then 15 : 1 = 90°: x° If the ratios are equal, The product of means = The product of extremes ⇒ 15 × x = 1 × 90° ⇒ 15x/5 = 90°/15 ⇒ x = 6° ∴ Angle made by minutes hand in 1 minute = 6°

Answer»

We know angle made by minutes hand in 15 m = 90°

Let angle made by minutes hand in 1 m = x°

Then 15 : 1 = 90°: x°

If the ratios are equal, The product of means = The product of extremes

⇒ 15 × x = 1 × 90°

⇒ 15x/5 = 90°/15

⇒ x = 6°

∴ Angle made by minutes hand in 1 minute = 6°
