Answer:
Patrick scored higher
Step-by-step explanation:
Shelia percentage is 87%
Patrick percentage is 91%
They must travel 682 miles because 596+612=1,208 and 1,890-1,208=682
12/3=4
4 divided by 17/18 equals to 4* 18/17=72/17= 4 4/17
Thus the answer is 4 4/17
We have been given that the upstream speed is
and the down stream speed is
.
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is 
Hence, 
Time upstream + time downstream = 6

lcm = 10

=> 
Cross multiplying, 
x = 20 miles .. Answer.
1.06, 1.16, 1.6, 1.62, 1.66
