well you have to see how far they have gotten after 4 hours. so 4*40=160 50*4=200. since it was opposite directions you add. so 160+200=360.

12r <br> r=1/6<br><br> Please show your work

Flauer [41]

Answer:

Step-by-step explanation:

If m = 4, z = 9 and r = 1/6

1. 3 + m = 3 + 4 = 7

2. z - m = 9 - 4 = 5

3. 12r = 12 × 1/6 = 2

4. 60r - 4 = 60(1/6) - 4 = 10-4 = 6

5. 4m - 2 = 4(4) - 2 = 16-2 = 14
