With base speed 0.3, what does `arcade(0.3, 0.15)` set the two motors to?

1. A.Left 0.15, right 0.45
2. B.Left 0.45, right 0.15
3. C.Both 0.3
4. D.Left 0.3, right 0.15

Answer Why?

1. A.−0.3
2. B.+0.3
3. C.0.7
4. D.0.2

Answer Why?

If Kp = 0.6 and error = 0.3, what is the correction?

2. B.0.18
3. C.0.3
4. D.0.5

Answer Why?
