During a hard sneeze, your eyes might shut for 0.43 s. If you are driving a car at 125 km/h, how far does it move during that time?
To find out how far the car moves during the time your eyes are shut, we need to calculate the distance traveled in 0.43 seconds at a speed of 125 km/h.
First, let's convert the speed from kilometers per hour to meters per second, as we need to use consistent units.
1 kilometer is equal to 1000 meters, and 1 hour is equal to 3600 seconds. Therefore, to convert 125 km/h to meters per second, we can use the following calculation:
Speed in meters per second = (125 km/h) * (1000 m/km) / (3600 s/h)
Speed in meters per second = 34.72 m/s (rounded to two decimal places)
Now, we can calculate the distance traveled during the 0.43 seconds by using the formula:
Distance = Speed * Time
Distance = 34.72 m/s * 0.43 s
Distance ≈ 14.93 meters (rounded to two decimal places)
Therefore, the car would move approximately 14.93 meters during the 0.43 seconds your eyes are shut.
