<span>1. h = -16t² + vt + c
⇒ vt = 16t² + h - c
⇒ v = 16t + (h-c)/t
2. c = 5 ft
t = 3s
h = 131 ft
v = 16*3 + (131-5)/3 = 48 + 42 = 90 ft/s
when t=0, velocity is not defined. That means at t=0, there is no velocity of the t-shirt or it is 0.

Speed = distance / time
given:
distance = 225 km and time = 2.5 hours
so
speed = 225 / 2.5 = 90 km per hour
Answer:
Speed = 90 km per hour
