Math Problem Statement

A rabbit travels at a constant speed. The table below shows the proportional relationship between the distance and time a rabbit travels. What is the constant of proportionality? Time in hours, x Distance in miles, y 2 • ? 3 4 • ? 6 6 • ? 9 8 • ? 12 10 • ? 15

The constant of proportionality is .

Solution

To find the constant of proportionality, we need to determine the ratio of the distance traveled (in miles) to the time (in hours) for each pair of data.

We have the following pairs of time and distance from the table:

  • Time = 2 hours → Distance = ?
  • Time = 3 hours → Distance = 6 miles
  • Time = 4 hours → Distance = ?
  • Time = 6 hours → Distance = 9 miles
  • Time = 8 hours → Distance = 12 miles
  • Time = 10 hours → Distance = 15 miles

The constant of proportionality kk is the ratio between distance and time, represented as:

k=Distance (y)Time (x)k = \frac{\text{Distance (y)}}{\text{Time (x)}}

Using the given dataTo find the constant of proportionality, we need to determine the ratio of the distance traveled (in miles) to the time (in hours) for each pair of data.

We have the following pairs of time and distance from the table:

  • Time = 2 hours → Distance = ?
  • Time = 3 hours → Distance = 6 miles
  • Time = 4 hours → Distance = ?
  • Time = 6 hours → Distance = 9 miles
  • Time = 8 hours → Distance = 12 miles
  • Time = 10 hours → Distance = 15 miles

The constant of proportionality kk is the ratio between distance and time, represented as:

k=Distance (y)Time (x)k = \frac{\text{Distance (y)}}{\text{Time (x)}}

Using the given

  • For time = 3 hours and distance = 6 miles: k=63=2k = \frac{6}{3} = 2

  • For time = 6 hours and distance = 9 miles: k=96=1.5k = \frac{9}{6} = 1.5

  • For time = 8 hours and distance = 12 miles: k=128=1.5k = \frac{12}{8} = 1.5

  • For time = 10 hours and distance = 15 miles: k=1510=1.5k = \frac{15}{10} = 1.5

Since the ratio (constant of proportionality) is consistently 1.51.5 in all cases, the constant of proportionality is 1.5.
