    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.

    your Correct answer: d
    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.
