Lin and Andre boned home from school at a steady pace. Lin biked 1.5km and it took her 5 minutes. Andre biked 2 km and it took him 8 minutes. Who is biking faster?

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

What properties allow transformation to be used as a problem solving tool
