Question

Which situation is most likely to show a constant rate of change?

A. The weight of a child compared with its age in months
B. The distance traveled by a truck driving at a constant speed compared with time
C. The cost of a new car compared with the number of tires it has
D. The outside temperature compared with the time of day

Answer 1

The distance traveled by a truck driving at a constant speed compared with time

Answer 2

The situation that is most likely to show a constant rate of change is:

B. The distance traveled by a truck driving at a constant speed compared with time

Explanation:

Since by constant rate of change we mean that the value is increasing or decreasing by a constant rate.

Hence, from the given options the situation that will represent a constant rate of change is:

B. The distance traveled by a truck driving at a constant speed compared with time.

( Since if a truck is driving at constant speed with time the distance traveled by it in a particular time interval will also be equal and hence, will result in a constant rate of change )
