Answer:
d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.
Step-by-step explanation:
d=vt
v=14m/s
t=18s
d= vt, (14m/s)(18s)
d=252m
 
        
                    
             
        
        
        
Answer:
3
Step-by-step explanation:
Using listing:


No other factors are possible.
Hence, 1, 3, 7 and 21 are factors of 21.
 
        
                    
             
        
        
        
Thank you for posting your question here. Please see below answers for the problem above:
a. to find the circumference of the tire you need to multiply 3.14 by 2.5:
 = 3.14 x 2.5
 = 7.85 to round of it will be 8
b. to get the number of times the tire have to rotate to travel 1 mile:
1 mile = 5,280 ft
1 rotation is 7.85 
5,280/7.85 = 672.611465
