i) Rest time is given by:
[tex]rest=final\text{ time of rest}-initial\text{ time of rest}[/tex]
Where:
Final time of rest = 13:15
Initial time of rest = 12:45
Therefore:
[tex]rest=13:15-12:45=30[/tex]
Answer i) 30 minutes
ii) The distance traveled after the rest is given by:
[tex]distance=final\text{ distance-initial distance}[/tex]
Where:
Final distance = 39 km
Initial distance = 18 km
So:
[tex]distance=39-18=21[/tex]
Answer ii) 21 km
