Yes, that's correct. All you do is add the two numbers together and then divide by 2!
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
10 x 25 = 250, well 20 x 25 is just double that, its 10 doubled x 25 so he probably just added it up. repeated addition really helps with times tables.
<span>3 is to 4 as 12 is to x, or 3/4 = 12/x </span>
