How many feet per second do you travel at 55 mph approximately?
Answer: C — 80 feet
To determine how many feet per second you travel at a speed of 55 miles per hour, you first need to convert miles per hour into feet per second. 1 mile is equal to 5,280 feet, and there are 3,600 seconds in one hour. Therefore, to convert 55 miles per hour to feet per second, you can use the following calculation: \[ \text{Feet per second} = \frac{55 \text{ miles/hour} \times 5,280 \text{ feet/mile}}{3,600 \text{ seconds/hour}} \] Calculating this gives: \[ \text{Feet per second} = \frac{55 \times 5,280}{3,600} \approx 80.67 \text{ feet/second} \] This rounds to approximately 80 feet per second. Thus, at 55 mph, you travel about 80 feet in one second. Therefore, this choice accurately reflects the conversion and provides a useful benchmark for understanding speed in a trucking context.
