Sanya can wash 7 bath towels in one wash, which will take 1 hour. She only has 2 hours in a day to do this task. If she has 98 bath towels, how many days will she need to wash all of them? Think carefully first, then make a decision:
Every day, Sanya can wash 7 x 2 = 14 bath towels. To wash all the towels, she will need 98 / 14 = 7 days. So, the answer is 7.
