Answer:
10 hours
Step-by-step explanation:
We have the equation of motion:
x = x0 +v0.t
with x0 is the point that you start to drive
v0 is the initial velocity
t is time
---------------------------
call Lucinda is A, Tom is B (for easy to calculation)
choose the time Lucinda start is start point
---------------------------
A: xA = 100 + 50.t
B: xB = 60.t
So two cars chasing each other when:
xA = xB
100+ 50.t = 60.t
=> t = 10 (hours)
