First you must state that the relationship is proportional. It is because it goes into the origin.
y = 2.5x
k = 2.5 And 2.5 is the constant of proportionality.
A) 25% = 25/100 = 0.25
b) 18% = 18/100 = 0.18
c) 40% = 40/100 = 0.40
d) 2% = 2/100 = 0.02
e) 0.15% = 0.15/100 = 0.0015
Answer:
3.54 and 1.04
Step-by-step explanation:
Given:
Two towns are 1,100 miles apart.
A group of hikers Starts from each town and walks down the trail toward each other..
They meet after a total hiking time of 240 hours.
If one group travels 2 1/2 mile per hour slower than the other group.
<u>Question asked:</u>
Find the rate of each group.
<u>Solution:</u>
Let speed of faster hiker = 
Speed of slower hiker = 
<u>As we know:</u>
<u />
Total distance between two town = Total combined speed of both hikers
Total combined time taken


Speed of faster hiker =
= 3.54 miles per hour.
Speed of slower hiker =
=

Therefore, speed of faster hiker is 3.54 miles per hour and speed of slower hiker is 1.04 miles per hour.
