Given:
Consider the complete question is "A speed walker covered  mi in
 mi in  hour. How far will he walk in 3/4 hours if he walks twice as fast?"
 hour. How far will he walk in 3/4 hours if he walks twice as fast?"
A speed walker covered  mi in
 mi in  hour.
 hour.
To find:
Distance covered by him if in 3/4 hour if he walks twice as fast.
Solution:
We have,

It means a speed walker covered  mi in
 mi in  hour.
 hour. 
If the speed is twice then he can cover double distance is same time.
Distance covered by him if in 3/4 hour if he walks twice as fast is

Therefore, distance covered by him is 9 mi.
 
        
             
        
        
        
Step-by-step explanation:
(x + y)^5 = 1·x^5·y^0 + 5·x^4·y^1 + 10·x^3·y^2 + 10·x^2·y^3 + 5·x^1·y^4 + 1·x^0·y^5

Answer:
b=i* or -i*
 or -i*
Step-by-step explanation:
11b^2-9=-68
11b^2=-59
b^2=-59/11
b=i* or -i*
 or -i*
"i" in this case is an imaginary number, equal to
