Question

A raft travels down river at a rate of 6 miles per hour. The total distance d in miles that the raft travels is equal to the rate times the number of hours h. What is the independent variable? * What is the dependent variable? * Write an equation for this situation. (using h and d) *

Answer 1

d=6h

Explanation:

Speed of the raft= 6 miles per hour

Total distance (d) of the raft= rate × number of hours

d=r*h

Independent variable is the number of hours(h)

Dependent variable is the distance (d)

Equation for the situation

d=r*h

d=distance

r=rate

h=number of hours

From the question,

r=6 miles per hour

Therefore,

The equation is

d=r*h

d=6*h

d=6h
