two trains leave the station at the same time, one heading west and the other east. the westbound train travels at 80 miles per
hour. the eastbound train travels at 60 miles per hour. how long will it take for the two trains to be 392 miles apart? do not do any rounding.
2 answers:
Answer:
ok the train goes 60+80=140 in 1 hour
140+140=280 2 hours
392-280=112
112/ the 60 miles and 80 miles is .80% of the hour so
60*.80=48 and 80*.80=64
48+64=112 so the trains will be 392 miles apart in 2.8 hours
Step-by-step explanation:
Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
