Answer:

<u>10</u>

Step-by-step explanation:

Formula :

  • aₙ = -5 + aₙ₋₁

Finding a₅ :

  • a₅ = -5 + a₄
  • a₅ = -5 + 20
  • a₅ = 15

Finding a₆ :

  • a₆ = -5 + a₅
  • a₆ = -5 + 15
  • a₆ = <u>10</u>

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
