A phone keeps track of the number of steps taken and the distance traveled. based on the information in the table, is there a proportional relationship between the two qualities?

there is no proportional relationship between the two qualities

Step-by-step explanation:

For two quantities to be proportional, it must follow the formula:

y = kx

where k = proiportionality constant

k = y/x

if y = 950, x = 1

inserting in the equation:

950= 1k

k = 950

The equation becomes: y = 950 × x

We check for other values. if k is the same, it is proportional

when y = 2852, x = 3

2852 = k × 3

k = 2852/3 = 950.67

when y = 5.1, x = 4845

4845 = k × 5.1

k = 4845/5.1 = 950

From the above, the value of k which is different is for the 2nd value.

Since they are not all the same, we say there is no proportional relationship between the two qualities
