First let's make both the miles and the hours ran improper fractions:

So, to find our miles per hour, we have to divide the miles by the hours to get: 
Answer:
the last one
Step-by-step explanation:
because you have two (-1) and that means it is not a function.
Answer:
15
Step-by-step explanation:
The formula for distance when given vertices is
√(x2 - x1)² + (y2- y1)²
Where we have points (x1,y1) and (x2,y2)
So, (-2,7) and (3, -3)
Distance = √(3 -(-2))² + (-3 -7)²
= √5² + (-10)²
= √25 + 100
= √125
= 15
Therefore, the distance between (-2,7) and (3, -3) is 15
Oh shucks man, I'm sorry bout that
Yeah I’m sorry I’m just responding bc I need points I hope u get your answer soon
