18 min<--->12 miles
60 min<---> (60 / 18) x 12 miles
= (10 / 3) x 12 miles
= 40 miles
Speed = 40 miles per hour

(12 miles / 18 minutes)(60 minutes / 1 hour) = 40 miles per hour

12 miles in 18 minutes
= 12 miles / 18 minutes
= (12 / 18 ) miles per minute
I expect you can divide 12 by 18, right?

if a mile a minute is 60 mph then 60 * (12/18) or 2/3rds of 60 mph, or
40mph
