Answer:
4y miles
Explanation:
Max : x miles per hour
Sven: y miles per hour slower
x-y is the speed for Sven
We know that distance = speed * time
Distance for Max = x*t
Distance for Sven = (x-y) * t = xt - yt
The difference in distance is Max's distance minus Sven's distance
xt - ( xt-yt)
xt - xt +yt
yt
Max is yt miles ahead where t is the time
The time is noon to 4 which is 4 hours
Changing t to 4
The distance ahead is 4y miles
