1. **State the problem:** A car and a motorcycle start from the same place at noon, traveling in the same direction.
2. **Define variables:** Let $m$ be the speed of the motorcycle in mph.
3. **Express the car's speed:** The car's speed is 30 mph slower than twice the motorcycle's speed, so car speed $c = 2m - 30$.
4. **Use the distance formula:** Distance = speed $\times$ time.
5. **Set up the equation for the distance difference after 2 hours:** The car is 20 miles ahead, so
$$2c - 2m = 20$$
6. **Substitute $c$:**
$$2(2m - 30) - 2m = 20$$
7. **Simplify:**
$$4m - 60 - 2m = 20$$
$$2m - 60 = 20$$
8. **Add 60 to both sides:**
$$2m - \cancel{60} + 60 = 20 + 60$$
$$2m = 80$$
9. **Divide both sides by 2:**
$$\frac{\cancel{2}m}{\cancel{2}} = \frac{80}{2}$$
$$m = 40$$
10. **Find car speed:**
$$c = 2(40) - 30 = 80 - 30 = 50$$
**Final answer:**
- Motorcycle speed = 40 mph
- Car speed = 50 mph
