Question

The distance a car travels is directly related to the time it travels. The distance is 300 miles when time is 5 hours. What is the constant of variation?

Answer 1

Because the distance a car travels is directly related to the time it travels, the distance varies directly with the time: d=a*t. "a" would be the constant of variation. Just substituted the given values(300 and 5) into the equation, and you would get 300=5a. Divide both sides by 5 and you get a=60. So, the constant of variation is 60
