Given:
Consider the complete question is "A speed walker covered 
mi in 
hour. How far will he walk in 3/4 hours if he walks twice as fast?"
A speed walker covered mi in 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 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.
11.45... to solve it, you add all of the numbers and then divide by the total number of numbers. so 126 divided by 11
How you write 8.216 in scientific notation; 8.216 * 10 ^ 3
10 ^ 3 = 10 to the 3rd power.
4+1 = 5
5 is the answer but you could also just subtract it a normal way
Answer:
12 x 24 = 288
32 - 24 = 8
8 x 12 = 96
