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
