Question

The time t required to drive a certain distance varies inversely with the speed r. If it takes 12 hours to drive the distance at 60 miles per hour, how long will it take to drive the same distance at 85 miles per hour?

Answer 1

Answer:

8.47 Hours

Step-by-step explanation:

The total distance covered in 12 hours with a speed of 60 mph

Distance = 12 x 60 = 720 miles

Now we are required to find the time taken if the same distance is travelled with a speed of 85 mph

Time = 8.47 hours
