Alonzo takes 12 minutes to run 6 times around a 400-meter track. Assuming he runs at a constant speed, how long does he take to

snow_lady [41]

Answer:

5 minutes to run 1 kilometer

Step-by-step explanation:

Alonzo takes 12 minutes to run 6 times around a 400-meter track.

6 times around a 400 m track

400 * 6 = 2400 meters

It take 12 minutes to run 2400 meters

2400 meters = 2400/1000 = 2.4km

distance = 2.4 km and time = 12 minutes

Now we find our constant speed

$Distance = speed * time$

2.4 = speed * 12

divide by 12 on both sides

speed = 0.2

so speed is 0.2 km per minute

Now we find out time when distance = 1km

Distance = speed * time

1 = 0.2 * t

divide by 0.2 on both sides

5 = t

So it take 5 minutes to run 1 kilometer

Karen's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Karen $5.50 per pound, and type

Lady_Fox [76]

Answer:

32 lb

Step-by-step explanation:

Let a = number of pounds of type A coffee used.

Let b = number of pounds of type B coffee used.

From the statement:

"This month's blend used three times as many pounds of type B coffee as type A"

we get this equation:

b = 3a

"Type A coffee costs Karen $5.50 per pound, and type B coffee costs $4.25 per pound."

She spend (in dollars) 5.50a + 4.25b, but since b = 3a, we get

5.5a + 4.25(3a) = 5.5a + 12.75a.

She spent $584, so

5.5a + 12.75a = 584

18.25a = 584

a = 32

She used 32 lb of type A coffee.

trasher [3.6K]

Answer:

1246 yards

Step-by-step explanation:

To find the yard of fencing she needs for he cows, we simply need to find the perimeter of the rectangular area.

The area is 200 yards by 423 yards.

The perimeter is the sum of all the sides of a rectangle and it is given by:

P = 2(L + B)

P = 2(200 + 423) = 2(623)

P = 1246 yards.

She needs 1246 yards of fencing.
