Answer:
90.5
Step-by-step explanation:
Velocity is a time-derivative of displacement or the height, in this case.
At maximum height, the velocity is 0 and the height is 128.
Substitute these values into both equations above,
From the first equation,
Substitute for 
.
Answer:
<em>1336miles.</em>
Step-by-step explanation:
From the question we are told that;
1km represents 0.62miles
1km = 0.62miles
We are to express 2155kilometers in miles.
2155km = x miles
Find x:
Divide both equations;
1/2155 = 0.62/x
Cross multiply;
1 * x = 2155 * 0.62
x = 1,336.1miles
<em>Hence the correct option is 1336miles.</em>
