6 multiple choice 2 points the time it takes to drive a certain distance varies inversely as the speed traveled. if it takes 8 hr at 60 mph to drive a certain distance, how long would it take to drive the same distance at 24 mph? 21 hr 24 hr 20 hr 23 hr

6 multiple choice 2 points the time it takes to drive a certain distance varies inversely as the speed traveled. if it takes 8 hr at 60 mph to drive a certain distance, how long would it take to drive the same distance at 24 mph? 21 hr 24 hr 20 hr 23 hr

Answer

Explanation:

Step1: Find the distance

Use the formula (d = s\times t). Given (s = 60) mph and (t = 8) hr. (d=60\times8 = 480) miles.

Step2: Calculate the new time

Use the formula (t=\frac{d}{s}). Now (d = 480) miles and (s = 24) mph. (t=\frac{480}{24}=20) hr.

Answer:

20 hr
