Question

The time spent to travel a certain distance varies inversely as a car's speed. If it takes 5½ hours to travel a certain distance at 60 miles per hour, how long will it take to travel the same distance at 50 miles per hour?
Select one:
a. 6.6 h
b. 6.9 h
c. 4.6 h
d. 4.2 h

Answer 1

Answer:

6.6h

Step-by-step explanation:

• So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 miles
• Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
• 330 miles divide by 50 miles per hour gives 6.6 hours
