aum · Answer

45 minutes is 3/4 hour.
Mary's speed = 30 / (3/4) mph = ?
John's speed = 200 / 3.5 mph = ?

This is essentially like your last question. First find out how many miles per minute Mary is driving, then do the same with John, but this time with John you must convert hours to minutes first
