Annex the bar graph that shows which improvement time is less, the new formula being more effective, with an average of 55 minutes and the average of the old formula is 75 minutes, which leads to the conclusion that the new formula is better than the previous one with a time difference of 20 minutes.
Answer:
The distance cover by Bell is 8 miles .
Step-by-step explanation:
Given as :
The distance cover by Mike = The distance cover by Pete = D miles
Let The distance cover by Bell = d miles
The distance cover by Mike = 15 miles + distance cover by Bell
i.e D = 15 + d ............1
Again
The distance cover by Pete = three time distance cover by Bell - 1 miles
i.e D = 3 × B - 1
Or, D = 3 d - 1 ............2
Now, Solving equation 1 and 2
So, 15 + d = 3 d - 1
Or, 3 d - d = 15 + 1
Or, 2 d = 16
∴ d = 
i.e d = 8 miles
So,The distance cover by Bell = d = 8 miles
Hence, The distance cover by Bell is 8 miles . Answer
10!
There's two halves in a whole. So we could do 5 x 2 to get our answer. Hope this helps!
