Hi there! :)
Answer:
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! :)
