The additional time needed would be 2 hours
Explanation:
For an object moving with a uniform motion (=constant velocity), the relationship between distance, time and velocity is
[tex]d=vt[/tex]
where
d is the distance covered
v is the velocity (also equal to the speed, since the motion is in a straight line)
t is the time taken
In the first situation in the problem, we have
d = 600 km is the distance
v = 50 km/h is the speed
So, the time taken is
[tex]t=\frac{d}{v}=\frac{600}{50}=12 h[/tex]
In the second situation, we have
d = 600 km
v' = 60 km/h
So the time taken is
[tex]t'=\frac{d}{v'}=\frac{600}{60}=10 h[/tex]
Therefore, the additional time taken is
[tex]\Delta t = t - t' = 12 - 10 = 2 h[/tex]
