The number of feet is 2460.63 feet
The given parameters are:
Speed = 90 kilometers/hour
Time = 30.0 seconds
The distance is calculated as;
Distance = Speed * Time
So, we have
Distance = 90 kilometers/hour * 30.0 seconds
Express hour as seconds
Distance = 90 kilometers/(3600 seconds) * 30.0 seconds
This gives
Distance = 0.75 kilometers
Convert to feet
Distance = 0.75 * 3280.84 feet
Evaluate
Distance = 2460.63 feet
Hence, the number of feet is 2460.63 feet
