Use the formula d=rt to find the value of the missing variable
d=42 feet, t=14 seconds
then r= ft. second
42 = r * 14
r = 42/14 = 21/7 = 3 ft/s
thank you! u r awesome... I wasn't too sure.. again thank you!
d=rt;d=100,t=25
To find the value of the missing variable (r) in the formula d = rt, you can rearrange the formula to solve for r. Divide both sides of the equation by t:
r = d / t
Plug in the given values:
r = 42 feet / 14 seconds
Simplify the expression:
r = 3 feet/second
Therefore, the value of the missing variable, r, is 3 feet/second.
