Question

To find the rate of speed (r) in the formula d = rt, you can rearrange the equation as follows:

2,058 = 4r
To solve for r, you can divide both sides by 4:
r = 2,058 / 4
r = 514.5
So, the rate of speed represented by the variable r is 514.5 miles per hour.

Answer 1

To calculate the rate of speed (r) in the equation 'd = rt,' you can divide both sides by the time variable. In the example 2,058 = 4r, dividing both sides by 4 yields r = 514.5 mph.

Step-by-step explanation:

To find the rate of speed (r) in the formula d = rt, you can rearrange the provided equation 2,058 = 4r to isolate r. By dividing both sides by 4, you obtain r = 2,058 / 4, which leads to r = 514.5. In this context, the variable r represents the rate of speed, equivalent to 514.5 miles per hour. The concept of speed as a physical quantity is discussed in various levels of physics education, highlighting the relationship between distance traveled and time taken, commonly represented as the equation speed = distance/time.
