a train leaves little rock and travel north at 85 kilometers per hour. another train leaves at the same time and travel south at 60 kilometer per hour. how long will it take before they are 290 kilometer apart
Answer provided by our tutors
let 't' be the time the trains need to travel to be 290 km apart
since distance = speed*time we have
85*t + 60*t = 290
by solving we find
t = 2 hours
