Answer:
Explanation:
Alright, lets get started.
Lets find slope for both bikes one by one
For bike 1 :
There are two points on the graph of Bike 1, these two points are (2,3) and (4,6)
So the slope for bike 1 is :
![(y_(2)-y_(1) )/(x_(2)-x_(1) )](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y2fllq9ixyl027z0lspq06siuzb64xnwsd.png)
So the slope for bike 1 is :
![(6-3)/(4-2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vkatkqenf4kvp6t3hrkwp5dxcsqaepnjrl.png)
So the slope for bike 1 is :
![(3)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/85tww783zdtzzps1k74cyql3cl3s1y42ha.png)
For bike 2 :
There are two points on the graph of Bike 2, these two points are (4,5) and (8,10)
So the slope for bike 2 is :
![(y_(2)-y_(1) )/(x_(2)-x_(1) )](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y2fllq9ixyl027z0lspq06siuzb64xnwsd.png)
So the slope for bike 2 is :
![(10-5)/(8-4)=(5)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/r4avg5yskv9iwdhhf8g2wzbysag03z88i7.png)
Hence Bike 1 will win the race as slope of line bike1 is greater than slope of line bike 2. So, answer is option D
