Step-by-step explanation:
sike you use what you got the first time
1 guest = 500ml
7 guests = 500ml × 7 = 3500ml = 3.5litres
1 litre = $1.50
0.5 litre = $1.50 ÷ 2 = $0.75
3.5litres = $1.50 + $1.50 + $1.50 + $0.75 = $5.25
answer is $5.25
For this case, the first thing we must do is define variables.
We have then:
x: time in minutes
y: distance traveled.
We then have the following equations:
For Kathleen:

For Arnob:

By the time Arnob reaches Kathleen we have:

From here, we clear the value of x.
We have then:


Answer:
it takes Arnob to catch up to Kathleen 75 minutes:
