Question 427315

remember:

the distance {{{d = s*t}}}...where {{{s}}} is speed and {{{t}}} is time

{{{d = s*t}}}......solve for {{{t}}}

{{{t=d/s}}}....plug in {{{d=158km}}} and a speed of {{{s=100km/h}}}

{{{t=158km/100(km/h)}}}.......cancel km and km

{{{t=158/100(1/h)}}}.........h is going in nominator

{{{t=158h/100}}}

{{{t=1.58h}}}.....or {{{t=1h_and_35min}}}
