Answer:
<em>Equation: 10t=400</em>
<em>It will take them 40 hours to be 400 miles apart.</em>
Step-by-step explanation:
<u>Constant Speed Motion</u>
If the speed of an object is v, the distance traveled in a time t is:
Ms. Ironperson travels at 50t (not speed, but a distance), and Mr. Thoro travels at 60t. Since the latter travels faster, the distance between them at time t is given by:
To be 400 miles apart, we set the equation:
10t=400
Solving:
t=400/10=40
It will take them 40 hours to be 400 miles apart.
Note: Some assumptions were made in this question:
- The rates are not speeds but distances
- The distances are in miles
At the rate of 84 words per 2 minutes, which translates to 42 words per one minute.
So in one minute she types 42*1=42 words
In 3 minutes she types 42*3=126 words
In 9 minutes she types 42*9=378 words
