ira [324]

Answer:

4.08 s

Explanation:

Let the passenger took "t" time to catch the train

so in this case the total distance moved by the train + 5 m = total distance moved by the passenger

so we will have

distance moved by train is given as

d_1 = \frac{1}{2}(0.6) t^2

also the distance moved by passenger

d_2 = \frac{1}{2}(1.2) t^2

so we will have

d_1 + 5 = d_2

0.3 t^2 + 5 = 0.6 t^2

0.3 t^2 = 5

t = 4.08 s

Anna35 [415]

Answer:

t= 1.2 hours

Explanation:

Define first di distance between the points, so

\bar{x}_{canoe}=2*(2+3)=10

\bar{x}_{water}=2*2=4

The distance is

d= \bar{x}_{canoe}- \bar{x}_{water}

d= 10-4 = 6miles

t = \frac{x}{v} = \frac{6}{2+3}

t= 1.2 hours
