Question

John wanted to impress his friends by winning the 200 yard dash at the track meet. if he runs 8.2 feet per second, how long will it take him to complete the dash? (round to the nearest tenth)

Answer 1

Answer:

Time taken by John to complete the dash will be 73.2 seconds

Step-by-step explanation:

Length of the dash is 200 yards

We will convert this length from yards to feet first.

∵ 1 yard = 3 feet

∴ 200 yards = 3×200

                     = 600 feet

Since John runs with a speed of 8.2 feet per second then we have to find the time to complete the dash.

Time = $\frac{\text{Distance}}{\text{Speed}}$

        = $\frac{600}{8.2}$

        = 73.17 seconds

        ≈ 73.2 seconds

Time taken by John to complete the dash will be 73.2 seconds.

Answer 2

Since a yard equals 3 feet, it would take him 73.1 seconds to finish the dash.
