Answer:

t= 03:21 h
Step-by-step explanation:
A constant speed means that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)
where x is distance and t time. The subtract is final value minus initial value
If xo=0 miles and to=0 h, then

We have distance, and speed so we need to calculate the time (how long)

t= 03:21 h

Answer:
Right skewed
Step-by-step explanation:
A skewed right distribution by definition is "one in which the tail is on the right side".Or on simple words when we have the following property:

Or equivalently:

A skewed left distribution by definition is "one in which the tail is on the left side". Or on simple words when we have the following property:

Or equivalently:

And for this case we can see that 
So on this case the best description for this distribution is right skewed.
