A. 60x/y B. y/60x C. 60y/x D. x/60y E. 60xy x hours = 60x MINUTES (since there are 60 minutes in each hour) So, the DISTANCE Tom travels = y miles, and his TRAVEL TIME = 60x minutes Speed = distance/time So, Tom's speed = y/(60x) Answer: B

==>You get miles:hours=y(miles):x(hours)=y(miles):60x(minutes), and from y:60x=some:1, you get some=y/60x. The answer is B. Answer: B

Speed is y/x means distance traveled in x hour = y miles
distance traveled in minutes = y/x*60 ( 1 hour = 60 min)
option B is correct

A. 60x/y B. y/60x C. 60y/x D. x/60y E. 60xy Tom goes y miles in = x hours or 60 mins * x How many miles can Tom go in = 1 min Required ratio = \(\frac{y}{60*x}\) = \(\frac{y}{60x}\)Answer B... _________________ Kindly press "+1 Kudos" to appreciate

Explanations are already there. We can also do it by substitution.
Assume x=1, y=30. So Mike covers 30 miles in 1 hour, or in 60 minutes. In 60 minutes, distance covered = 30 miles In 1 minute, distance covered = 30/60 = 1/2 or 0.5 miles
So we have to look for an option that gives us answer as '1/2' when we substitute x with 1 and y with 30. That is only option B.
Hence B
(Please note that in my opinion, using simple algebra as others have done is the best way to solve this question. I have just given an alternate method)

To determine his rate in terms of miles per minute, let’s convert hours to minutes. x hours = 60x minutes; thus: (y miles)/(60x minutes) = y/60x miles per minute Answer: B
