Boo Radley wants to run a 1500m race with an average velocity of 6.00m/s. After running the first 500 m, Boo notices that the elapsed time is 1 min 40 seconds. Panicking, he accelerates for "t" seconds at 0.20 m/s² and then finishes the race at his new faster speed. He makes it just in time. How long did he accelerate for? (Use 5 sig. figs. in your answer)

Hint: The answer is between 5 and 10 s.

3. The attempt at a solution

I figured out that he has 150 s to run 1000m, so I divided that and got 6.6666, then divided that by .2 and took the square root of that answer to get 5.7706s. Went to the teacher today and told me I was way off. I have tried to graph it as well, but I am just stuck and don't know what to do. PLEASE HELP.
