A truck

A truck left Znojmo at 7 a.m. He drove to Ostrava at an average of 56 km/h. 15 minutes later. A car went out of Ostrava at the same route from Znojmo at 64 km/h. What time did both vehicles pass and at what distance from Znojmo, if you know that the road distance between the two cities is 224 km?

Result

t = 9:00 hh:mm Wrong answer
z =  112 km

Step-by-step explanation:

s=224 km v1=56 km/h v2=64 km/h t1=15 min h=15:60  h=0.25 h  s1=v1 t1=56 0.25=14 km x=(ss1)/(v1+v2)=(22414)/(56+64)=47=1.75 h t=7.00+t1+x=7.00+0.25+1.75=9=9:00 hh:mm
z=v1 (t1+x)=56 (0.25+1.75)=112 km
