​

Answer 1

Step-by-step explanation:

The correct Answer is A 240 degree

Answer 2

Answer:

(A) 240º

Step-by-step explanation:

At 10' o'clock:

In 1 minute, minute hand moves 6 degree

In 40 mins, minute hand moves: 6*40 = 240 degree

Angle traced by minute hand between 10 : 00 a.m. to 10 : 40 a.m will be 240 degree.

Alternatively,

Divide 360° by 60 as there are 60 minutes in an hour.

Angle made by minute hand in 1 minute = 360°/60

                                                                     =6°

Angle made by minute hand in 40 minutes = 6° × 40

                                                                      = 240°

Angle traced by minute hand between 10 : 00 a.m. to 10 : 40 a.m will be 240 degree.
