Sagot :

The distance in kilometers, d, expressed as a function of time in hours, t is  d = 3t km

From the question,

A pedestrian is walking at a speed of 3 km/h.

To express the distance in kilometers, d, as a function of time in hours, t

We will use the formula connecting speed, distance and time.

The formula connecting speed, distance and time is

[tex]Speed =\frac{Distance}{Time}[/tex]

Let speed = s

distance = d

and time = t

∴ We can write that

[tex]s = \frac{d}{t}[/tex]

Since the given speed, s = 3km/h

Then, we can write that

[tex]3 =\frac{d}{t}[/tex]

Then, the distance, d expressed as a function of time, t will be

d = 3t km

Hence, the distance in kilometers, d, expressed as a function of time in hours, t is  d = 3t km
