Question

On planet FACE, there are 10 days in a week. There are 36 hours in a day and each hour has 90 minutes while each minute has 60 seconds. As on Earth, the hour hand covers the dial twice every day. Find the approximate angle between the hands of the clock on FACE when the time is 14:40 a.m.?

a. 83 b. 74 c. 129 d. 65​

Answer 1

Answer:

I think b 74 or d 65 should be the answer

Answer 2

Answer: c . 129

Step-by-step explanation:

twice a day means

36/2=18 hrs. || 90min=360°

18hr=360° || 1min=4°

1hr=20° ||

now,

for 14:40am

For hr hand 14 ,

(20×14)+((40/90)×20)=288.888 = 289 approx.

Now for min hand 40,

40×4=160.

Now,

for angle, we will find the difference of hour hand and min hand,

|289-160|= 129° approx.
