Question

A vehicle travels at a steady rate of 35 miles per hour. A student will graph the total distance, D, as a function of the time in hours, h, showing the distance for 1 to 3 hours. If the student counts by 10's, what should be the largest value on the D-axis of his or her graph so that the scale is the most appropriate for the given information?

Answer 1

The largest value on the D-axis of the graph should be 105 miles.

Step-by-step explanation:

To find the largest value on the D-axis of the graph, we need to determine the total distance traveled by the vehicle for 1 to 3 hours. Since the vehicle travels at a steady rate of 35 miles per hour, we can use the formula distance = rate x time. Plugging in the values for time (1 to 3 hours), we can calculate the corresponding distances:

• For 1 hour: distance = 35 mi/h * 1 h = 35 miles
• For 2 hours: distance = 35 mi/h * 2 h = 70 miles
• For 3 hours: distance = 35 mi/h * 3 h = 105 miles

Based on these calculations, the largest value on the D-axis should be 105 miles to ensure the scale is appropriate for the given information.

Answer 2

110 is the answer i got it wrong on my test and that was it.
