Answer:
(x - 3)mph * > 2x
Explanation:
KC's total rides in hours = 2x
KC's average speed = x
David's average speed :
3 mph less than KC's average speed = (x - 3)mph
David's total ride in hours in a month is more than KC's, that is ( >2x)
From the equation:
Speed = distance / time
Distance = speed * time
Total distance of miles David rides each month:
(x - 3)mph * > 2x
