K takes less time than M to travel a distance of 30 miles. K travels 1/3 mile per hour faster than M. If x is K's rate of speed in miles per hour then find K's time for the distance in terms of x
.
Let x = K's rate of speed
.
This problem you must apply the "distance formula":
d = rt
where
d is distance
r is rate or speed
t is time
.
For, k to travel 30 miles:
Solving the formula for t:
d = rt
t = d/r
.
K's time:
t = 30/x hours (I believe this is what the problem is asking for)
.
