Solution:
Given that,
Distance = 5 km
Time taken = 1 minute
We know that,
[tex]1\ minute = \frac{1}{60}\ hour[/tex]
Find the average speed:
[tex]Average\ speed = \frac{distance}{time\ taken}[/tex]
Substituting the values we get,
[tex]Average\ speed = \frac{5}{\frac{1}{60}}\\\\Average\ speed = 5 \times 60}\\\\Average\ speed = 300[/tex]
Thus average speed of a race car is 300 km/hr
