Answer:

time(t) = 7.60805

Step-by-step explanation:

Givens

Rv = 513

Rate = 67 3/7

t = ??

Formula

Rv = R * t

Solution

513 = 67 3/7 * t

Change the 3/7 to a decimal

3÷7 = 0.428571 repeating

513 = 67.428571... * t                 Divide by 57.42857

513 / 67.438571 = t                    Carry out the division

7.6081  =  t                                  Switch

t = 76081 minutes
