The best estimate is 33/40
Hope this helped
Let t be time and r be rate, then if time varies inversely with the rate, the equation is
. If it takes 5 hours to drive a fixed distance at a rate of 80, we can sub those values in to solve for the constant of variation, k.
. Solve for k by multiplying 5 and 80 to get that k = 400. Now let's find a new time t when r is a rate of 70. We will use that k value to do this:
and find that it will take 20 hours to drive the distance at 70 mph when it takes 5 hours to drive the distance at 80 mph. Makes sense that it takes longer to drive a fixed distance when you are going slower.

Write an equivalent expression
To do this, we simply write as a product of two factors.
Express 4b as 2 * 2b
Express 2m as 2 * m
Factor 2 out of the expression:
Hence:
An equivalent expression is:
