The given situation involves a rate of change that you may assume to be constant. Write a statement that describes how one variable varies with respect to another, give the rate of change numerically (with units), and use the rate of change rule to answer the questions.You drive along the highway at a constant speed of 62 miles per hour. How far do you travel in 4.1 hours? In 6.3 hours? Write a statement that describes how one variable varies with respect to another.
A. Your distance traveled changes with respect to time at a rate of 62 miles per hour. The rate of change is 62 mi/hr. In 4.1 hours, you travel 254.2 miles. In 6.3 hours, you travel 390.6 miles. B. Your distance traveled changes with respect to time at a rate of 62 miles per hour. The rate of change is 62 mi/hr. In 4.1 hours, you travel 127.1 miles. In 6.3 hours, you travel 195.3 miles. C. Your distance traveled changes with respect to time at a rate of 62 miles per hour. The rate of change is 62 mi/hr. In 4.1 hours, you travel 190.65 miles. In 6.3 hours, you travel 292.95 miles. D.
