Answer:
3 miles per min
Step-by-step explanation:
3 miles x 15 (min) = 45 mph
For number 16, keep the slope and plug in the values of x and y and solve for the y intercept. For 20 take the opposite reciprocal and then plug in the values of x and y and solve for y intercept. For number 24 and 25 convert both into slope intercept form (y=mx+b) and see if they are parallel or perpendicular
