Question

How much time would it take (in seconds) for an Olympic skier to finish a 2.6 km race at
an average velocity of 28 m/s? (Hint 1 km = 1000 m & your units must match)

Answer 1

That's pretty simple, we have;

• Total distance to be covered by olympic skier = 2.6 km = 2.6 × 1000 = 2600.0 m
• Average velocity = 28 m/s

We know that;

• Speed = Distance / Time

And..

• Time = Distance/speed

Put all the values;

• Time = 2600/28
• Time = 92.85 sec

Therefore, the total time taken will be 92.85 sec.
