Question

7.) The time needed to travel a certain distance varies inversely with the rate of speed. It takes 8 hours to travel a certain distance at 36 miles per hour.

a.) Write an equation to describe the situation. (Note: the variable that represents time must be on one side by itself.)





b.) How long will it take to travel the same distance at 60 miles per hour?

Answer 1

Sorry I need points

Answer 2

t=time

v=speed

t=k/v

8hr=k/36 mi/hr

k=288 mi

t=288 mi24 mi/hr =12 hours.

-------------------

The distance is 288 miles by multiplying 36 by 8.

divide that by 24 mph, and it is 12 hours.
