Question

Mrs brown wants to cook 5 dishes on a stove with 2 burners. The times she needs to cook each dish are 40min,15min,35min,10min and 45min. What is the least amount of time mrs brown needs to cook all 5 dishes

Answer 1

Answer:

75 minutes

Step-by-step explanation:

First cook 40 and 45 min dishes on separate burners. Then after 40 min put 35 min dish to be cooked on that burner. This will take 75 minutes time.

On second burner put firstly 15 min and then 10 min dish or vice versa as it doesn't matter. This second burner will take 70 minutes which is less then first one.
