Question

6 MATH CHALLENG Mr. Jacob's class has silent reading for twenty minutes every day after lunch recess. Mrs. Clark's class has silent reading on Monday, Wednesday and Friday for half an hour. In four weeks, how many more minutes will the students in Mr. Jacob's class spend reading than the students in Mrs Clark's class?​

Answer 1

200

Explanation:

Mr. Jacob's class reads every day for 20 minutes, which ends up being 20 * 28 because there are 28 days in four weeks. That equals 560

Mrs. Clark's class reads 3 days a week for 4 weeks, so 3*4 = 12. The number of minutes her class reads is 30 minutes so 30*12 = 360.

560-360=200
