What is the angle made by hours hand in one minute?

1.	What is the angle made by hours hand in one minute?
Answer» We know angle made by hours hand in 1 hour (60 minutes) = 30° Let angle made by hours hand 1 minute = x° Then 60 : 1 = 30°: x° If the ratios are equal, The product of means = The product of the extremes ⇒ 60 × x = 1 × 30 ⇒ 60x/60 = 30/60 = 1/2 ⇒ x = 1/2 (or) 0.5° ∴ Angle made, by hours hand in 1 minute = 1/2° ° (or) 0.5°

Answer»

We know angle made by hours hand in 1 hour (60 minutes) = 30°

Let angle made by hours hand 1 minute = x°

Then 60 : 1 = 30°: x°

If the ratios are equal,

The product of means = The product of the extremes

⇒ 60 × x = 1 × 30

⇒ 60x/60 = 30/60 = 1/2

⇒ x = 1/2 (or) 0.5°

∴ Angle made, by hours hand in 1 minute = 1/2° ° (or) 0.5°
