Answer i need it ! will give brainliest and 50 ! campers were walking with a speed of 4.5 mph on the way to their rest area and were coming back to the camp with the speed of 4 mph, thus spending 15 more minutes to cover the distance. what was the distance between the camp and the rest area?

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

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
