I would recommend multiplying the first equation by -2 and the second equation by 3 so that you can get + and -12 for the y terms to cancel.
Use the slope formula which is y2-y1/x2-x1. -1-4/5-(-2)= -5/7
Velocity equals distance over time, so take 260 divided by 4 and get an average speed of 65 mph.
Answer:
2/5 are girls so 40
