Answer:
1.753418e+17
Step-by-step explanation:
Distance = speed * time
for curtis d = st = 6t (where t is the time that he walks)
sean walks 20 seconds longer than curtis so we have the equation
d = s(t+20) = 5(t+20)
as the distances are the same we have
So sean has walked 100+20 = 2
6t = 5(t+20)
6t = 5t + 100
t = 100
so Sean walks 120 seconds when they had both walked the same distance.
