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:
![x=v\cdot t](https://tex.z-dn.net/?f=x%3Dv%5Ccdot%20t)
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:
![D=60t-50t=10t](https://tex.z-dn.net/?f=D%3D60t-50t%3D10t)
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
Answer:
I think it would become 20 because if you were to half seven, it would be about 3, and if 7 m/s2 makes around 40N, half that and you would get 20.

Answer:
$2,400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 10000 × 0.06 × 4 = 2400
I = $ 2,400.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 6% per year
for 4 years is $ 2,400.00.
