We can approach this question in terms of equivalent ratios
Jim drives k miles in 50 minutes
We're comparing miles traveled to minutes elapsed.
Jim travels k miles for every 50 minutes.
Our ratio is k miles/50 minutes
How many minutes will it take him to drive 10 miles, at the same rate?
So, our ratio is 10 miles/? minutes
So, our equation is: k/50 = 10/?
Cross multiply to get: (?)(k) = (50)(10)
Simplify: (?)(k) = 500
Solve for ? to get: ? = 500/k
Answer: A
