Question

A top fuel dragster covers the quarter mile in 4.5 seconds. What is it's speed in miles per hour

Answer 1

Answer: The speed of top fuel dragster is 200 miles/hr

Explanation:

We are given:

Speed of top fuel dragster = quarter mile in 4.5 seconds = 0.25 mil/4.5 sec

To calculate the speed of top fuel dragster in miles per hour, we use the conversion factor:

1 hr = 3600 seconds

Converting the speed in miles per hour, we get:

$\Rightarrow (\frac{0.25mil}{4.5s}\times (\frac{3600s}{1hr})\\\\\Rightarrow 200mil/hr$

Hence, the speed of top fuel dragster is 200 miles/hr

Answer 2

Distance in Miles (.25) x 3600 (seconds in an hour) / time in seconds = 200 MPH. Drag racing calculates the top speed via a speed trap starting 66 feet from the finish line.
