[tex]\sf\large\underline{Given:}[/tex]
[tex]\sf\large\underline{To\: Find:}[/tex]
[tex]\sf\large\underline{Solution:}[/tex]
[At 1st convert the time in second here]
[As we know that, 1hour=3600second]
[tex]\rm{\implies Distance=2*3600}[/tex]
[tex]\rm{\implies Distance=7200m}[/tex]
[tex]\rm{\implies Distance=3*3600}[/tex]
[tex]\rm{\implies Distance=10800m}[/tex]
[tex]\rm{\implies Total\: distance=7200+10800}[/tex]
[tex]\rm{\implies Total\:distance=18000m}[/tex]
[tex]\rm{\implies Total\:distance=18000\div 1000}[/tex]
[tex]\rm{\implies Total\:distance=18km}[/tex]
Hence,
