Homework Statement


A rabbit runs in a straight line with a velocity of +1.5 m/s for a period of time, rests for 10s, and then runs again along the same line at +0.60 m/s for an unknown amount of time. The rabbit travels a total distance of 1200 m, and its average speed is 0.80 m/s. (a) What is the total time the rabbit spends running at 1.5 m/s? (b) How long does it spend running at 0.60 m/s?

Homework Equations


V = d/t
a = (v2-v1) /t
I don't know if there is any other formulas you could use for this question

The Attempt at a Solution



t = d/V
Total time = 1200 / 0.8 = 1500 sec-------------------------------------------
Answer for a: 340 sec
Answer for b: 1200 sec

I want to know how to get these answers
 
Physics news on Phys.org
1.5x + 0.6y = 1200(0.8)

Hopefully that helps. If you don't understand where I got that from or what to do from here, let me know.
 
what does that equation even mean? Are the "x" and "y" the time intervals?
