Answer:
Alicia
Explanation:
First, convert the mixed fractions into improper fractions
Alicia
Distance: 5 1/2 = 11/2 = 5.5 miles
Time: 1 2/5 = 7/5 = 1.4 hours
Carlos
Distance: 8 1/8 = 65/8 = 8.125 miles
Time: 2 1/2 = 5/2 = 2.5 hours
Henry
Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles
Time: 1 1/10 = 11/10 = 1.1 hours
Zoe
Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles
Time: 1 3/10 = 13/10 = 1.3 hours
After that, divide the distance by the time
Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )
Carlos = 8.125 / 2.5 = 3.25
Henry = 3.6 re / 1.1 = 3.3 reoccuring
Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )
Looking at these answers, we determine which rate is the greatest
Alicia = 3.93
Carlos = 3.25
Henry = 3.3 re
Zoe = 3.54
Alicia hiked the highest rate.
