Answer:
The rest stop is 9 miles away from the camp
Step-by-step explanation:
4.5 to
4 back
let x=time
4.5x=4(x+15)
4.5x=4x+60
.5x=60
x=120 minutes=2 hours
2 *4.5=9miles
2.25 hours (2 hours 15 min) * 4= 9miles
The rest stop is 9 miles away from the camp
The time taken on the trip to the rest area is 2 hours while that on the return trip is 2.25 hours or 2 hours and 15 minutes. The distance between the camp and the rest area of 9 miles.
Given:
The speed of campers on the way to the rest area is 4.5 mph.
The speed of campers on the way to the camp is 4 mph.
Let the time taken on the way to the rest area of t hours. The time on the way back will be t+0.25 hours. (15 minutes is 0.25 hours).
The distance d between the camp and the rest area will be the same for both the trips.
So, mathematically, it can be written as,
[tex]d=4.5\times t=4\times (t+0.25)\\0.5 t=1\\t=2\rm \; hours\\d=4.5t\\d=4.5\times 2\\d=9\rm\; miles[/tex]
Therefore, the time taken on the trip to the rest area is 2 hours while that on the return trip is 2.25 hours or 2 hours and 15 minutes. The distance between the camp and the rest area of 9 miles.
