Answer:
42 i think
Step-by-step explanation:
900 / 60 = 15
So, the plane traveled 360,000 meters in 15 minutes.
Generally, we do per hour. So, 15 mins * 4 = 60 mins or 1 hour. Because we multiplied the time by 4, we also need to multiply the distance by 4. 360,000 * 4 = 1440000 meters. The plane was traveling at 1440000 meters per hour.
However, it does not make sense to use meters for this long of a distance. I am going to convert it into miles (let me know if the question asks for a different unit of distance). 1 mile equals 1609.34 meters. Divide 1440000 by 1609.34 to get how many miles. 1440000 / 1609.34 = 894.7767408.
Therefore, the plane is going about 895 miles per hour--pretty fast!
<span>First find how many grams are in 15.87kg and how many meters are in 30.48cm
15.87kg x 1000g/kg = 15, 870g
30.49cm x 1m/100cm = 0.3049m
Then, set up a proportion.
0.3049m/15, 870g = 1m/x g
Cross multiply to get..
0.3049x = 15, 870
Divide for x and there you are.</span>Source(s):Myself.1004 <span>· 8 years ago
