<PRE><B>Question 673243</B>
use the formula distance=rate x time

the distance is 75 ft
the time is 1/4 seconds
let r=rate

75=r1/4
rewrite 1/4 as .25
75=r.25
divide both sides by .25
300=r

the train is moving 300 ft per second
to find out how many feet it travelled in 5 seconds we multiply 300x5
answer: it will travel 1,500 ft in 5 seconds</PRE>
