Answer:
What is the m part?
Step-by-step explanation:
Answer:
15 miles
Step-by-step explanation:
Let 
be the miles in the circular park path, 
the time Louisa takes to finish and 
the time Calvin takes to finish both in hours.
Then , the longitude is equal to the velocity times the time used to finish. So
And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:
Three equations, three unknowns, the system can be solved.
Equalizing the equation with x :
In this last equation replace with the other equation and solve:
With Louisa's time find x:
To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket.
25.5 - 5.2 = 20.3 Litres
In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units.
20.3L = 20300mL
You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel.
20300 <span>÷ 800 = 25.375
That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26.
Hope this helps :) </span>
