Question

sets and functions chapter


1) A plane is flying at a speed of 500 km per hour. express the distance d travelled by the plane as function of t in hours.

Answer 1

Answer:

d = 500t

Step-by-step explanation:

Let us look at it in that we need to write the equation of the line in the form :

y = mx + c

In this equation :

m = is the gradient of the line.

x = the independent variable

c = the y intercept

y = the dependent variable.

In this case we will use the parameters d and t.

We can represent this as :

d = mt + c

d = the distance in kilometers.

t = time in hours

m = speed = 500 km/h

To write the distance d as a function of time t we have :

d = 500t

In this way we have written d as a function of t.

Answer 2

Answer:

d = 500t
