Distance 3615

Honza left home at 8 a.m. on foot at an average speed of 4 km/h. At 11 a.m., dad followed him on a bicycle at an average speed of 40 km/h. How long and at what distance from home will dad catch up with Honza?

Correct answer:

t =  0.3333 h
s =  13.3333 km

Step-by-step explanation:


4(t+(11-8))=40t

4·(t+(11-8))=40·t

36t = 12


t = 12/36 = 0.33333333

t = 1/3 ≈ 0.333333

Our simple equation calculator calculates it.
s=40 t=40 0.3333=13.3333 km
