Question

An Olympic athlete set a world record of 9.95 seconds in the 100-meter dash. Did his speed ever exceed 36 kilometer per hour during the race?

Answer 1

To determine if the athlete's speed exceeded 36 kilometers per hour during the race, we need to convert the world record time of 9.95 seconds for the 100-meter dash into kilometers per hour. The athlete's speed did exceed 36 kilometers per hour during the race.

Step-by-step explanation:

To determine if the athlete's speed exceeded 36 kilometers per hour during the race, we need to convert the world record time of 9.95 seconds for the 100-meter dash into kilometers per hour. We can use the formula:

Speed (km/h) = Distance (km) / Time (h)

First, we need to convert the distance from meters to kilometers by dividing it by 1000: 100 meters / 1000 = 0.1 kilometers.

Next, we need to convert the time from seconds to hours by dividing it by 3600: 9.95 seconds / 3600 = 0.00276 hours.

Using the formula, the athlete's speed is: 0.1 km / 0.00276 h = 36.23 kilometers per hour.

Therefore, the athlete's speed did exceed 36 kilometers per hour during the race.
