Quizplus · Accepted Answer

Using d = rt and plugging in d = 560 and t = 8, we get:
560 = r * 8
Dividing both sides by 8, we get:
t = 70
Therefore, the answer is choice C. Using the formula d = rt, we can solve for t by dividing both sides by r. 
So, t = d/r. 
Substituting d = 560 and t = 8 into the equation, we get 
8 = 560/r. 
Solving for r, we get 
r = 560/8 = 70. 
Therefore, the correct answer is C) t = 70.
