Do you have a picture to go with it?
Answer:
23.52 miles
Step-by-step explanation:
Let us find the number of miles that they would have run.
Kana starts at 9:35 a.m. and runs at an average rate of 7 mph.
Let the time she has spent so far be t.
Speed is given as:
s = d / t
where d = distance and t = time
=> d = s * t
Therefore, for Kana:
d = 7 * t = 7t _____________(1)
Ji-Hun starts at 10:00 am (25 minutes after Hannah) and runs at an average rate of 8 mph.
25 minutes = 25/60 hour = 0.42 hour
So, his time (compared to Kana's) is t - 0.42.
therefore, for Ji-Hun:
d = 8 * (t - 0.42)
=> d = 8t - 3.36 ____________(2)
Equating (1) and (2):
7t = 8t - 3.36
=> 8t - 7t = 3.36
t = 3.36 hours
Therefore, let us find d:
d = 7 * 3.36 = 23.52 miles
So, Ji-Hun will catch up to Kana after 23.52 miles.
I would use 100 as the denominator because it can not be simplified as a whole number
Solution: The total cost of the gift including the tax = $55.80
The amount paid by Montel = $14
The amount paid by Raymond is
Therefore, Raymond paid $18.6
The amount paid by Emily is
25% of 55.80
Therefore, Emily paid $13.95
We also know that the remaining amount is paid by Leanne.
Therefore, the remaining amount is:
Total amount - Amount paid by Montel, Raymond and Emily
The amount paid by Leanne is $9.25
We clearly see, Raymond has paid $18.6, which is the greatest part of the cost $55.80
