At 55 mph, how far does a driver travel in 1.5 seconds?

To find out how far a driver travels at 55 mph in 1.5 seconds, it's useful to first convert the speed from miles per hour to feet per second.

1 mile is equivalent to 5,280 feet and there are 3,600 seconds in an hour. Therefore, we can convert the speed as follows:

55 miles/hour × (5,280 feet/mile) ÷ (3,600 seconds/hour) = 80.67 feet/second (approximately).

Next, we calculate the distance traveled in 1.5 seconds. Since distance can be calculated with the formula:

Distance = Speed × Time,

we can substitute the numbers:

Distance = 80.67 feet/second × 1.5 seconds ≈ 120 feet.

Thus, the distance traveled at a speed of 55 mph in 1.5 seconds is approximately 120 feet. This demonstrates why the correct answer is indeed the option indicating 120 feet.
