Question

NEED HELP ASAP PLEEEASE :( I need to write an equation for this:

Train A leaves a station at 8:00 and travels at 100 km per hour towards the next city.  One and a half hours later, Train B, an express, leaves the same station, traveling at 160 km per hour along the same route. At what time will Train B overtake the slower train?

Answer 1

Let 'T' be the number of hours after 8:00. ... Distance 'A' = 100 T. ... Distance 'B' = 160 (T-1.5). ... At the time when the later, faster train catches up with the earlier, slower one, the distances are equal. Write an equation that says they're equal, solve it for 'T', and add 'T' hours to 8:00.
