Answer 1

The car's speed in feets per second is 79.2, Hence, it will cover a distance of 158.4 feets in 2 seconds.

Car's speed in miles per hour = 54 miles per hour

Recall :

• 1 mile = 5280 feets
• 1 hour = 3600 seconds

Car's rate in feet per second

• 54 miles per hour = (54 × 5280 × 1/3600) feet per second = 79.2 feets per second.

• Distance in 2 seconds :
• Distance = speed × time
• Distance = 79.2 × 2 = 158.4 feets

Therefore, the car will cover a distance of 158.4 feets in 2 seconds.
