A train leaves a station at noon. train is 180 miles from its destination at 12:45 pm and 90 miles from its destination at 2:15.
how far is station from destination?225 miles

S = D/T = 90miles/90 min = 1 mile per min or 60 mph
note: got 3 3/4 hrs( noon to 3:45 pm)
D = TS = 3 3/4 hrs(60mph) = 225 miles from station to destination

at what time will the train reach the destination? 3:45 pm
t=d/s = 90 miles/60mph = 1 1/2 hrs
2:15 pm + 1:30 = 3:45 pm
