So of you set it equal to each other 150m+3m = 9m -3m = -3m you get 150m=6m and you divide by 6 on each side so it comes out to 25 minutes... I think...
The answer is A. When you multiply 9 by 25, you get 225. When you multiply 3 by 25 you get 75 but you add 150 which gives you 225, which means it took the turtle 25 minutes to catch up to the snail.
