Sarada drove the same route to work each morning, Monday through Friday, in a particular week. On Monday and Tuesday she averaged 20 miles per hour, and on her three remaining work days she averaged 30 miles per hour.
Quantity A : Sarada’s average speed for all five morning commutes
Quantity B : 26 miles per hour
For the above Q, the answer is B. Could anyone explain how?
