A) The rearranged formula is:
r = d/t
B) Using the above formula we can see that the rate is 25,000 m/h.
C) Here we have the linear equation:
d = (25,000 m/h)*t
Here we need to use the formula:
distance = rate*time.
To solve this formula for the rate, we need to divide both sides by the time, so we will get:
rate = distance/time.
Writing this with the given variables:
r = d/t.
b) Now we know that the distance is 800,000 meters and the time is 4 hours, then the rate will be:
r = 100,000m/4h = 25,000 m/h
The rate is 25,000 meters per hour.
c) Now we wil get the linear equation:
d = r*t
d = (25,000 m/h)*t
This linear equation gives the distance traveled in a time t.
