Step-by-step explanation:
To solve this equation I used the quadratic formula.
1. Place the units into the following formula. -b+-sqrtb^2-4ac
2a
2. After placing the units into the formula it should be -1+-sqrt1+24
2
3. This should leave you with two possible answers -3 and 2 after solving it. The answer can not be negative of course cause there is no such thing as a negative time. So the answer has to be 2.
