When and Where will walker A pass Walker B?

Question

Suppose two people began walking in the same direction at different average speeds. Walker A starts at the 0.5 meter mark and waljs at a speed of 1m/s. Walker B starts at the 2-meter mark and walks at a speed of 0.5 m/s. When and where will walker A pass walker B?

Answer 1

distance=rate*time

walker A walks 1.5 m more than walker B because A starts at the 0.5 m mark and B starts at the 2 m mark (2-0.5=1.5)

d+1.5=1*t for walker A

d=0.5*t for walker B

0.5t+1.5=t

1.5=t-0.5t

1.5=0.5t

15=5t

t=15/5=3 seconds elapses when walker A catches up to walker B

d=0.5*3

d=1.5 m

walker B walks 1.5 m starting at the 2 m mark and ends up at the 3.5 m mark when walker A catches him

walker A starts at the 0.5 m mark and walks for 3 seconds at a speed of 1 m/sec, therefore, walker A walks 3 m starting at the 0.5 m mark and ends up at the 3.5 m mark where again he catches up to walker B
