That's not the question you asked.

d = r*t
t = d/r

first you need a distance formula: d=s%2At...=> t=d%2Fs

if a car doing s=80%28km%2Fh%29 and traveled d=73.8km, than a time t is:
t=d%2Fs
t=73.8km%2F80%28km%2Fh%29
t=73.8cross%28km%29%2F80%28cross%28km%29%2Fh%29
t=73.8h%2F80
t=0.9225h...convert to minutes
t=55.35min ...convert 0.35 to sec
t=55min_and_21sec
