Question 915677
The fast cyclist:
{{{30(miles/hour)*t=12*miles}}}
{{{30t=12}}}
{{{t=12/30}}}
{{{t=2/5}}}
OR
{{{t=0.4}}} hours
OR
{{{t=24/60}}}, meaning time for the fast cyclist was 24 minutes.


The slow cyclist traveled a distance {{{24*(2/5)=48/5=highlight_green(9.60)}}} miles in that time.


Unfinished laps for the slow cyclist:
{{{highlight((12-9&3/5)miles*4(laps/mile))}}}
(just work through the basic arithmetic.)
