Question

Kendra and Patricia both leave the internet cafe at the same time, but in opposite directions. If Patricia travels 7 mph faster than Kendra and after 5 hours they are 175 miles apart, how fast is each traveling?

Answer 1

They would be at the same distance even if one stood still, and the other traveled at the sum of their speed. In this case, to travel 175 miles in 5 hour, you need a velocity [tex]k+p=\frac{175}{5} mph[\tex]. (Divide, or grab a calculator). Then, you know [tex] p= k+7[\tex], just substitute and you get the two values.
