I. Was trying to type it :O
OpenStudy (skullpatrol):
Distance traveled = rate * time traveled
$$d=rt$$
OpenStudy (anonymous):
D=√(x2-x1)^(2)+(y2-y1))
OpenStudy (skullpatrol):
That is the formula for points on a plane, This is a rate-time-distance word problem, right?
OpenStudy (anonymous):
Yea

Have you used the formula d=rt before?
OpenStudy (anonymous):
Not really
OpenStudy (skullpatrol):
I hope you are familiar with distance (d) and time (t), so that leaves rate (r) as the distance traveled per unit of time traveled, right?
OpenStudy (anonymous):
Aha

Making a sketch may help with word problems.
