t = 8:53 h Wrong answer
s =  5.3 km

Step-by-step explanation:

v1=6 km/h v2=50 km/h a=24 km t2=8+30/60=217=8.5 h  s=v1 (t8.00) d=v2 (tt2) s+d=a s=6 (t8.00) d=50 (t8.5) s+d=24  s6t=48 d50t=425 d+s=24  Pivot:Row1Row2 d50t=425 s6t=48 d+s=24  Row3Row1Row3 d50t=425 s6t=48 s+50t=449  Row3Row2Row3 d50t=425 s6t=48 56t=497  t=56497=8.875 s=48+6t=48+6 8.875=5.25 d=425+50t=425+50 8.875=18.75  d=475=18.75 s=421=5.25 t=871=8.875=8:53 h
