Answer:

B

Step-by-step explanation:

25 seconds=1/144 hour

1/4 miles(0.25miles)    for   1/144 hour

so the speed= 0.25/(1/144)=0.25x144=36

Using the principle of dimensional analysis to convert speed in miles per second to miles per hour, the correct statement is (1/4 miles) / 25 seconds) = 36 miles per hour.

Speed in miles per second :

  • Distance / time

Speed in miles per second = (1/4 miles) / 25 seconds)

Recall :

1 hour = 3600 seconds

25 seconds = (25 / 3600) = 0.0069444 hour

Hence,

(1/4 miles) / 25 seconds) = (1/4 miles) / 0.0069444 hr)

(1/4 miles) / 25 seconds) = 36 miles per hour.

Therefore, the correct expression is (1/4 miles) / 25 seconds) = 36 miles per hour.
