How many fewer miles was the first trip than the second trip?

Question

A bicycle group took two trips. On the first trip, they averaged 87 miles per day for 4 days and 78 miles per day for 3 days. On the second trip, they averaged 94 miles per day for 5 days and 69 miles per day for 2 days. How many fewer miles was the first trip than the second trip?

Answer 1

1st: 87 miles per day for 4 days and 78 miles per day for 3 days

2nd trip 94 miles per day for 5 days and 69 miles per day for 2 days

1st trip total miles = 87(4)+78(3) = 348+234 = 582

2nd trip total miles = 94(5)+69(2) = 470+138 = 608

608-582 = 26 miles less for the 1st trip

close to the 26 miles in this problem, 4% more though
