Answer:
in 3 seconds the train should travel 462 feet
Step-by-step explanation:
So, first, we convert the miles into feet.
105 x 5280 = 554400
This means the train travels 554400 feet per hour.
then, we convert the hour, into second.
Since an hour has 60 minutes, and a minute has 60 seconds, we simply multiply:
1(hour) x 60(minutes) x 60(seconds) = 3600
So the train moves 554400 feet every 3600 seconds.
To get how many feet it travels in one second, we divide this by 3600.
3600/3600 and 554400/3600
1 and 154.
For every second the train travels 154 feet.
Then we simply multiply them by 3.
3x1 and 3x154, which equals:
3 and 462.
So the train travels 462 feet every 3 seconds.
I tried to explain this as simply as I can.
I hope its all correct.
