If it reaches its maximum height a t=3 its velocity must be zero at t=3
dy/dx=0 at t=3
dA/dx=4x+12=24 at t=3 so this does not apply
dB/dx=-4x+12=0 at t=3 and B=13 at t=3 so B applies
dC/dx=-4x-12=-24 at t=3 so this does not apply
dD/dx=-4x-12=-24 at t=3 so this does not apply
dE/dx=-4x-12=-24 at t=3 so this does not apply
So only quadratic B: reaches a maximum height of 13 feet at 3 seconds.
Answer: 5 1/2 hours
Step-by-step explanation:
1 hour = 12 miles
2 hours = 24 miles
3 hours =36 miles
4 hours = 48 miles
5 hours = 60 miles
6 hours = 72 miles
66- 60 = 6. 6 is half of 12.
In conclusion, it will take Tavyon 5 1/2 (or 5.5) hours to bike 66 miles.
Hope this helps!
