Znojmo

From Znojmo to Brno started truck with a trailer at an average speed 53 km per hour. Against him 14 minutes later from Brno started car with an average speed of 1.2-times greater than the truck.

How long and how far from Znojmo, they meet if the distance Znojmo - Brno is 65 km?

Correct result:

t =  41.08 min
s1 =  36.3 km

Solution:

v1=53 km/h v2=1.2v1=63.6 km/h 14 min=0.233333333333 h v1t+v2(t0.233333333333)=65 t(53+63.6)=65+14.84 t=0.685 hod t=41.08 min 
s1=v1t=530.685=36.3 km



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
