A cattle train left Miami and traveled toward New York. 14 hours later a diesel train left traveling at 45km/h in and effort to catch up to the cattle train. After traveling for four hours the diesel train finally caught up. What was the cattle train's average speed?

Answer 1

Sure hope they were on different tracks

let speed of of cattle train be x mph
when they met, cattle train went 18 hrs
distance gone by cattle train = 18x miles

speed of diesel train = 45 mph
when they met, diesel went 4(45) or 180 miles

Ahhh, but they went the same distance when they met
18x = 180
x = 10

cattle train went 10 mph
