I'm completing the missing data to solve the problem. Time= 8 hours.

Answer:

The man would travel 240 Km. Choice (a)

Explanation:

Rate of change

We are given the distance driven of 180 km in a time of 6 hours. We'll find the distance traveled if the man keeps driving at the same rate by 8 hours.

The rate of change of the distance over time is called velocity (as a vector) or speed (as a scalar). The speed is calculated as the ratio of the distance x by the time t:


\displaystyle v=(x)/(t)


\displaystyle v=(180)/(6)

v=30\ km/h

If we want to calculate the distance, we must solve the equation for x:

x=v.t

For a time of t=8 hours:

x=30*8=240

The man would travel 240 Km. Choice (a)
