For this case we have to, so that both runners finish at the same time, Dave must also reach 88 seconds.
[tex]Dave\ runs\ to\ \frac {440} {55} = 8\ yards\ per\ second\\Jack\ runs\ to\ \frac {440} {88} = 5\ yards\ per\ second[/tex]
With respect to the times we have:
[tex]88-55 = 33[/tex]
Dave must have a 33-second disadvantage.
This means that in those 33 seconds of difference Jack runs:
[tex]5 * 33 = 165 \ yards[/tex]
So, Dave must lose 165 yards to get to Jack
Answer:
165
