First we can find out how many miles he travels each hour.
# of miles he travels per hour = 174 miles / 3 hours
# of miles he travels per hour = 58 mph
He travels 7 hours so multiply the # of miles he travels per hour by 7.
58mph x 7h = 406 miles
Martin can travel 406 miles in 7 hours.

Answer:
The Alans's average for the course is 84.5
Step-by-step explanation:
We are given
There are 4 tests, A Term paper and a Final examination.
Score = 92, 78, 82, 90.
Term paper score = 80
Final examination score = 86
Weighted mean = ∑ w.f/∑w
also the sum of all the weights is 100% = 1
weighted mean = 15%*92 + 15%*78+15%*82+15%*90+20%*80+20%*86/1
= 51.3 + 33.2
= 84.5
Therefore the Alans's average for the course is 84.5
