A motorist traveling at 72km/h has his eyes shut for 0.45seconds during a hard sneeze.calculate the distance covered by him during his time interval

Answer 1

To calculate the distance covered by the motorist during the 0.45 seconds, we need to convert the speed from km/h to m/s.

First, let's convert 72 km/h to m/s:
1 km = 1000 m
1 hour = 3600 seconds

Speed in m/s = (72 km/h) * (1000 m/km) * (1/3600 h/s)
= 20 m/s

Now, we can calculate the distance covered using the formula:
Distance = Speed * Time

Distance = 20 m/s * 0.45 s
Distance = 9 meters

Therefore, the motorist covers a distance of 9 meters during the 0.45-second interval.
