Question

If The hour hand of a clock moves −30° every hour. How many degrees does it move in 2 ⅕ hours?

Answer 1

Answer:

The hour hand of a clock moves -66* in 2 1/5 hours.

Step-by-step explanation:

2 x -30 = -60, and 1/5 of -30 is -6, and -60-6=-66 degrees.

Answer 2

Answer:

it moves -66 degrees

Step-by-step explanation:

because every hour it moves -30 so we times that by 2 wich is -60

we then have -60

After we would divide -30 degrees by 1/5 to find the change

That would equel -66 degrees so we now know the rate of change and we can also check it by multiply 5 by 6 witch would give us 30 or -30 so

Anwer -66 degrees
