2. Initially you are driving at \( 55 \mathrm{mi} h r \). If you come to rest in \( 7.5 \mathrm{~s} \) while traveling \( 450 \mathrm{ft} \), what is your average speed while stopping? (There are \( 5280 \mathrm{ft} \) in one mi.) A. \( 55 \mathrm{mi} / \mathrm{hr} \) B. \( 0.016 \mathrm{ft} / \mathrm{s} \) C. \( 120 \mathrm{ft} / \mathrm{s} \) D. \( 60 \mathrm{At} / \mathrm{s} \)
