Question

Find the unit rate (constant of proportionality) of the distance traveled.
Number of hours
0.25 1.5 2.5 3
Distance traveled (km) 3 18 30 36

Answer 1

Answer:

12.

Step-by-step explanation:

if to re-write the given condition, then

$\frac{3}{0.25} =\frac{18}{1.5} =\frac{30}{2.5} =\frac{36}{3} ;$

it is clear, the required constant is 12 (12 per hour).
