Speed = [tex] \frac{distance}{time} [/tex]

240 = [tex] \frac{1440}{time} [/tex]

Rearrange;

time = [tex] \frac{1440}{240} [/tex]

time = 6 hours

speed times time=distance
st=d
we want ot find time so isolate t
st=d
divide both sides by s
t=d/s

distance=1440
speed=240
t=1440/240=6
the times was 6 hours since mph his miles per HOUR
