2/3 hours = minutes help me find the answer

2/3 hours is equivalent to 40 minutes.

Step-by-step explanation:

Divide an hour, (60 minutes) by three to get 20, which is equivalent to a third. So to put it into perspective:

1/3: 20

2/3: 40

3/3(1): 60

Hope it helps!

40 minutes

Step-by-step explanation:

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .

t = 3
