Speed*Time = Distance

Speed*65 = s

Speed \(= \frac{s}{65}\)

When distance is r miles,

\(\frac{s}{65}*time = r\)

\(time = \frac{65r}{s}\)

Answer is (A)

E. rs/65


Official Explanation



Here we have a rate question, so we can set it up with a fraction that includes the relevant units:

(65 minutes)/(s miles)

We want to get r miles in the denominator without changing the value of the rate, so we can multiply by a form of 1:

(65 minutes)/(s miles)*(r/s)

The s's in the denominator cancel, leaving us with r miles. The numerator becomes (65 r)/s minutes.

The correct answer is (A).
