Here are three motion problems involving algebra:

### Problem 1: 
**Two cars moving towards each other:**
Car A is 120 miles away from Car B. Car A is moving towards Car B at a speed of 40 miles per hour, and Car B is moving towards Car A at a speed of 30 miles per hour. How long will it take for the two cars to meet?

### Problem 2:
**A boat traveling upstream and downstream:**
A boat can travel 20 miles downstream in 2 hours, but it takes the boat 5 hours to travel the same distance upstream. What is the speed of the boat in still water and the speed of the current?

### Problem 3:
**A cyclist's journey:**
A cyclist covers a certain distance in 2 hours when traveling at 12 miles per hour. The cyclist decides to travel the same distance at a speed of 15 miles per hour. How much time will the cyclist save by traveling at the faster speed?

**Tip:** In motion problems, distance is often calculated using the formula:  
\[ \text{Distance} = \text{Speed} \times \text{Time}. \]
