There are 3600 seconds in 1 hour.
Multiply feet per second by 3600 to get feet in 1 hour:
150 x 3600 = 540,000 feet in 1 hour.
1 mile = 5280 feet.
Divide feet per hour by 5280 to get miles per hour:
540,000 / 5280 = 102.27 miles per hour.
For this case we have the following equation:
h = -16t2 + 64t + 80
To find the maximum height, we derive the equation:
h = -32t + 64
We match zero:
-32t + 64 = 0
We clear t:
t = 64/32
t = 2
We substitute the value of t in the given equation:
h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
h (2) = 144
Answer:
The maximum height is 144 feet and the time to reach this height is 2 seconds.
P. S. The inequality sign changed or flipped when there's a negative figure involved.

Answer:
Temperature is the measure of hotness or coldness expressed in terms of any of several scales. An example would be "The cup of beans are boiling hot and has a temperature of 100 °C, whereas the water in the tub is just comfortably warm, with a temperature of about 38 °C. Although the water in the tub has a much lower temperature, it has greater thermal energy".
