Carla spends 10 minutes sharpening her knife and 3 times that amount of time peeling vegetables. How much time does she spend on these activities total?
First find the total time Carla spends peeling vegetables: 10 minutes * 3 = <<10*3=30>>30 minutes
Then add the time she spent sharpening her knife: 30 minutes + 10 minutes = <<30+10=40>>40 minutes
