Question

Solve the equation "d equals r times t" for r, given d = 210 miles and t = 7 hours.

a) r = 30
b) r = 15
c) r = 20
d) r = 25

Answer 1

To solve for r in the equation d = r times t, divide both sides by t to get r = d / t. By substituting the given values, r = 210 / 7 = 30.

Step-by-step explanation:

To solve the equation d = r times t for r, given d = 210 miles and t = 7 hours, we can substitute the given values into the equation. So, 210 = r times 7. To solve for r, we divide both sides of the equation by 7. Therefore, r = 210 / 7 = 30.
