1. Write the equation for Willa catching up to Roger:
500 + 20t = 40t
2. Subtract 20t from both sides:
500 = 20t
3. Divide both sides by 20:
t = 25
4. Therefore, the time it took Willa to catch up is:
t = 25
2. Subtract 20t from both sides:
3. Divide both sides by 20:
4. Therefore, the time it took Willa to catch up is:
