Question

What will be the angle between the hands at 4.40 pm?

Answer 1

Answer:

120

Step-by-step explanation:

We know, 60 min=1 hour

so, 40 min=2/3 hour

In 1 hour, the clock rotates 360 degrees

so, in 2/3 hour the clock rotates 360*2/3 degrees

                                                    =240 degrees

Again, in 12 hours, the clock rotates 360 degrees

so, in 4 hours the clock rotates (360*4)/12 degrees

                                                   =120 degrees

therefore, at 4.40 pm, the angle between the hands=(240-120) degrees

                                                                                      =120 degrees(ANS)

Answer 2

Answer:

Remember that

hour ×30-min×11÷2 gives us the angle between the minute and hour hand..

so putting the values

4×30-40×11÷2=-100°

As we know there is no -ve sign for angles..So,Ur Ans is 100°...
