Amelia is driving her car at a constant speed. If she knows her speed and the time she has been driving, what formula should she use to calculate the distance she has traveled?

• d = s / t

• d = s - t

• d = s + t

• d = s × t

Freya is driving her car through a busy city. Sometimes she speeds up to catch a green light, and other times she slows down due to traffic. What type of motion is Freya experiencing?
