Question

Keith ran in a marathon. It took him 3 hours and 2 minutes to run 26 miles. If he ran at the same rate for the whole race, how many minutes did it take him to run each mile? (1 hour = 60 minutes)
A.) 6 minutes


B.) 7 minutes


C.) 8 minutes


D.) 9 minutes

Answer 1

Distance Keith ran = 26 miles

Time it took
= 3 hours 2 minutes = [(3 * 60) + 2] minutes = (180 + 2) minutes = 182 minutes

Hence, 

Speed (Rate) = $\frac{Distance}{Time} = \frac{26}{182} = \frac{13}{91} = \frac{1}{7}$ miles per minute

Hence,

Time taken to complete 1 mile
= $\frac{Distance}{Speed} = \frac{1}{ \frac{1}{7} } = 1 * \frac{7}{1}$
= 7 minutes 

Hence, the answer is B.
