Answer:
18 yards
Explanation:
Since it takes 1/2 minute to go 3/4 minutes, and we want to know how long it takes to go 12 minutes, you can divide 12 by 1/2, which is 24, then multiply 24 by 3/4ths, and you get 18.
6 mins
An ant can crawl 3/4 of a yard in 1/2 minute. How long will it take for the ant to crawl 12 yards?
Ant crawls 3/4 of a yard in = 1/2 min = 60/2 sec = 30 sec
Ant crawls 12 yards in = 12 * 30 = 360 sec = 360/60 = 6 minutes
