<span>Uphill distance = 1 4/5 = 9/5 = 18/10 km
Downhill Distance = 2 7/10 = 27/10 km
Total Uphill and Downhill = 18/10 + 27/10 = 45/10 = 4.5 km
Hence total level ground = Total race km - (Uphill + Downhill)
=10 - 4.5 = 5.5 km
Hence the answer is 5.5 km.</span>
Answer:
Instantaneous Velocity at t = 1 is 20 feet per second
Step-by-step explanation:
We are given he following information in the question:

B) Instantaneous Velocity at t = 1

A) Formula:
Average velocity =

1) 0.01

2) 0.005 s

3) 0.002 s

4) 0.001 s

Answer is 3.75%
3.75% = 0.0375
0.0375 + $2,100 = <span>$78.75</span>
