Simultaneously 6052

Trenčín is 120 km from Bratislava. The average speed of a cyclist traveling from Trenčín towards Bratislava is 20 km/h.
Calculate the average speed of the passenger car that left Bratislava compared to the cyclist if the cyclist and the passenger car left simultaneously and met after 90 minutes.

Correct answer:

v2 =  60 km/h

Step-by-step explanation:

s=120 km v1=20 km/h t=90 min h=90:60  h=1.5 h  s = v t s = (v1+v2) t  v2=(sv1 t)/t=(12020 1.5)/1.5=60 km/h
