You can put this solution on YOUR website!

a train traveled d=22.5mil in t=25min
convert minutes to hours: 1+Minute+=+0.01666666667+Hours
25min=25%2A0.01666666667h
25min=0.41666666675h
now find the rate or speed v
d=v%2At
v=d%2Ft
v=22.5mil%2F0.41666666675h
v=%2822.5%2F0.41666666675%29%28mil%2Fh%29
v=53.999999989200000002159999999568%28mil%2Fh%29...round it
v=54%28mil%2Fh%29
so, at this rate train will travel in d=54%28mil%2Fh%29%2A2h...=> d=54%2A2%28mil%2Fcross%28h%29%29cross%28h%29

d=108mil
