Given that one batch of cupcakes takes about 17 minutes to bake.
We have to find the time taken for 10 batches of cupcakes to bake.
If it takes 17 minutes to bake one batch then it'll take 10 x 17 = 170 minutes to bake 10 batches to bake.
We know that 1 hour = 60 minutes. So, 170 minutes = 2 hours and 50 minutes.
