Question

At what time between 4 and 4:30’0 clock, the hands of a clock are perpendicular to each other?

​

Answer 1

Answer:

$\huge\underline{\bf\red{Answer}}$

At 4 o'clock the distance between the two hands is 20minutes.

When they are at 15minutes distance, they are perpendicular to each other

. The time taken 5 and (5 + 30) = 5 and 35minutes.

∴ minutes hand is 55 minutes ahead of hour hand in 60minutes.

Answer 2

Given :- At what time between 4 and 4:30’0 clock, the hands of a clock are perpendicular to each other ?

Answer :-

Let at 4 : M angle between them is 90° .

so,

→ 30 * 4 - (11M/2) = 90

→ (240 - 11M) / 2 = 90

→ 240 - 11M = 180

→ 11M = 240 - 180

→ 11M = 60

→ M = 5(5/11)

therefore, at 4:5(5/11) the hands of a clock are perpendicular to each other .
