Kalin walks at a steady rate of 3 2/3 mph. How long will it take her to walk 8 1/2 miles

This is a inelastic equation, so we use (m1+m2)vf = m1v1+m2v2, where m1 is 4 kg, m2= 9kg. The start with no velocity so Vf=0, meaning the left side is 0. m1v1=4 times 2 =8, We subtract to the left side and divide by m2, 9kg. v2 = 8/9 heading west.

It is 120 because 300 times 2/5 is 120
