Answer:
Speed is 171.6 ft/s and distance is 1716 feet
Step-by-step explanation:
Given that,
The speed of a parachute = 117 miles per hour.
1 mph = 1.47 ft/s
117 mph = 171.6 ft/s
We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,
d = vt

Hence, this is the required solution.
If the value depreciates 8.6%, it is 91.4% of what it was the year before. The value can be modeled by
y = 19500(0.914)^x
