You can put this solution on YOUR website!

remember:
the distance d+=+s%2At...where s is speed and t is time
d+=+s%2At......solve for t
t=d%2Fs....plug in d=158km and a speed of s=100km%2Fh
t=158km%2F100%28km%2Fh%29.......cancel km and km
t=158%2F100%281%2Fh%29.........h is going in nominator
t=158h%2F100
t=1.58h.....or t=1h_and_35min
