If you divide miles by minutes, the answer will have units of 
miles per minute, which is exactly what you want.
(1 mile) / (10 minutes) = 1/10  mile/minute = 0.1 mile per minute

Answer: A medium in which speed of light is more is known as optically rarer medium and a medium in which speed of light is less is said to be optically denser medium. For example in air and water, air is raer and water is a denser medium.

Answer:
47.4 m
Explanation:
When an object is thrown upward, it rises up, it reaches its maximum height, and then it goes down. The time at which it reaches its maximum height is half the total time of flight.
In this case, the time of flight is 6.22 s, so the time the ball takes to reach the maximum height is

Now we consider only the downward motion of the ball: it is a free fall motion, so we can find the vertical displacement by using the suvat equation

where
s is the vertical displacement
u = 0 is the initial velocity
t = 3.11 s is the time
 is the acceleration of gravity (taking downward as positive direction)
 is the acceleration of gravity (taking downward as positive direction)
Solving the  formula, we find
