Hey Friends, Remember about old days we usually do those Trains, Man, Bridge, Cycle ..etc questions. Those were called Distance = Rate * Time mathematics queries.
So here again, just for fun......
Since an equation remains true as long as you divide through by the same non-zero element on each side, this formula can be written in different ways:
* To find rate, divide through on both sides by time:
Distance
Rate = -----------
Time
Rate is distance (given in units such as miles, feet, kilometers, meters, etc.) divided by time (hours, minutes, seconds, etc.). Rate can always be written as a fraction that has distance units in the numerator and time units in the denominator, e.g., 25 miles/1 hour.
* To find time, divide through on both sides by rate:
Distance
Time = -----------
Rate

Train A leaves the station traveling at 30 miles per hour. Two hours
later train B leaves the same station travelling in the same
direction at 40 miles per hour. How long does it take for train B to
catch up to train A?
If train A is going 30 miles/hour, then the amount of distance it can
go in a certain time (call it t) is:
30 miles/hour * t hours = 30t miles
The second train starts out 2 hours later, so for it the time it is
travelling is t-2. That menas that train B (going 40 miles per hour)
can go this distance in t-2 hours:
40 miles/hour * (t-2) hours = 40(t-2) miles
The question says that train B catches up with train A (which mean
that they go the same distance), so that means:
30t = 40(t-2)
Solve for t to find the number of hours the trains were traveling.
