Lizzy: Javier exercised for 50 minutes every day for one week. Sanda exercised for 90 minutes on each of three days. How many minutes did Javier and Sanda exercise in total?.
Me: Hmmm, let me think. I think this is the detailed solution:
Javier = 50 * 7 = 350 minutes. Sanda = 90 * 3 = 270 minutes. Total = 350 + 270 = 620 minutes. Together Javier and Sanda exercised for 620 minutes. Final answer: 620.
