Thanks for your questions. Your problem was –

If a man drives a car at a speed of 50 km per hour; then calculate the distance covered by the man in 10 minutes if he is driving at the same speed constantly.

Let’s we see how?
I’m trying to solve your problem and explain in details.  now let’s see –

Your question’s details Explanation:

It is given that man is driving at a speed of 50 km/hr for 10 minutes.
We know that, distance = speed * time———(i)

After substituting the value of speed and time in this formula we get,
Distance = 50 km/hr * 10 minutes——-(ii)

Now, 1 hour = 60 minutes Therefore, x hours = 10 minutes → x = 10 / 60 → x = 0.1667 hours.

Now, substituting the value of ‘x’ in equation (ii), we get,
Distance = 50km/hr * 0.1667 hr
∴ Distance = 8.335 km
Hence, the correct answer is option d.
