The cyclist moves at a speed of 20 km / h to the north. At the same time, an east wind blows at a speed of 10 km / h. What is the apparent wind speed for a cyclist?
Vvelocity = 20 km / h.
Vwind = 10 km / h.
V -?
Since the speed of the cyclist Vbicycle and the wind speed Vwind are oppositely directed, the wind speed relative to the cyclist V will be their sum: V = Vbicycle + Vwind.
V = 20 km / h + 10 km / h = 30 km / h.
Answer: the wind speed relative to the cyclist will be V = 30 km / h.
