Question 1137464: Can anyone out there help me with this? I do not understand how to solve this.
Over a specified distance, rate varies inversely with time. If a car on a test track goes a certain distance in one-half minute at 146 mph, what rate is needed to go the same distance in two-thirds minute?

------
rate varies inversely with time. If a car on a test track goes a certain distance in one-half minute at 146 mph, what rate is needed to go the same distance in two-thirds minute?
------
r, rate
t, time
k, variation constant
First sentence means, .
The fact that the time units involved in the next part of description are not the same is not a problem here.
Second sentence gives t=1/2 and r=146. Use these to get a value for k.

Formula is .
You can look into the units for k, if you want to.
