Question

A car's distance traveled is monitored over time. The results are displayed in this table.

Time (h) 1 2 3 4
Distance traveled (mi) 55 110 165 220
What is the constant of proportionality of this proportional relationship?

Enter your answer in the box.

Answer 1

55

Explanation:

Let,

Constant = k

k = h/mi

k = 110/2

k = 55 mi/h

Hence,

The constant of proportionality is 55

Answer 2

• k = 55

Explanation:

Proportional relationship:

• y = kx

We have:

• x = 1, y = 55
• x = 2, y = 110

Find the value of k:

• 55 = k*1
• k = 55

or

• 110 = k*2
• k = 55
