Charles run at a rate of 12 kilometers per hour. what is charles speed in meters per minute?

Hi there! :)

Charles runs at a rate of 200 meters per minute.

Step-by-step explanation:

First off, you need to know that 1 hour is equal to 60 minutes.

Let's start by calculating Charles' speed in kilometers per minute. Then we'll transform the kilometers into meters.

So, Charles runs at a rate of 12Km every 60 minutes and you want to know how many Km he runs in 1 minute.

In order to answer your question, you'll need to use the cross product method:

12 Km  →  60 minutes

x Km   →  1 minute

(12 × 1) ÷ 60 = x Km

12 × 1 = 12

12 ÷ 60 = x Km

12 ÷ 60 = 0.2

0.2 = x Km

Now, you need to know that 1 km is equal to 1000 meters.

You'll need to use the cross product another time to transfor your speed in kilometers per minute into meters per minute:

1 Km      =  1000 meters

0.2 Km  =  x meters

(1000 × 0.2) ÷ 1 = x meters

1000 × 0.2 = 200

200 ÷ 1 = x meters

200 ÷ 1 = 200

200 = x meters

There you go! I really hope this helped, if there's anything just let me know! :)

it would be 6xy and -16xy.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
