Question

$3.00/hour = ____ cents/minute? a. 3.4 b. 5 c. 1.8 d. 300

Answer 1

1$ = 100 cents,    1 hour = 60 minutes

$3.00/hour =  (3*100) cents / (1*60)minutes
 
                   =  300 cents/60 minutes
 
                   = 5 cents/minute

Option b.

Answer 2

Answer:

b. 5

Step-by-step explanation:

∵ 1 hour = 60 minutes and 1 dollar = 100 cents,

Given,

Rate is $ 3.00/hour

1 hour = 3 dollars,

⇒ 60 minutes = 3 dollars

⇒ 60 minutes = 300 cents

⇒ 1 minute = $\frac{1}{60}\times 300$ = 5 cents

Hence,

$3.00/hour = 5 cents/minute

Therefore, OPTION 'b' would be correct.
