- Time (t) is basically how many seconds or minutes you factor into the given function. 16(time in exact seconds or minutes)^2+40(time in exact seconds or minutes) +5
- The +5 can only be where the cannonball was initially fired from logically. The Velocity formula is already there for you to plug the time into^^^
(I used time in minutes/seconds to try and explain what the function is asking)
As the left number increases by 1, the right number increases by 4. So as you can see, the left numbers go 3-4-5 while the right numbers go 12-16-20. So the answer is 10:40 because 10x4=40.
