Swimming pool

Thaddeus set off on foot to the swimming pool, which is 18 km from his residence. The trip took him two and a half hours. An hour later, his brother Viliam met him on his bicycle, whose journey took three-quarters of an hour.
a) Show the described situation graphically
b) Determine from the graph how many minutes Viliam will catch up with Thaddeus

Correct answer:

x =  25.7143 min

Step-by-step explanation:

s=18 km t1=2.5 h t2=43=0.75 h Δ=1 h  s1=s2 v1=s/t1=18/2.5=536=7.2 km/h v2=s/t2=18/43=18:43=18 34=318 4=372=24 km/h  v1 (t+Δ)=v2 t 7.2 (t+1)=24 t  16.8t=7.2  t=16.87.2=0.42857143  t=730.428571  x=t min=t 60  min=0.4286 60  min=25.714 min=7180 min=25.7143 min
