Two cities

Cities A and B are 200 km away. At 7 o'clock from city A, the car started at an average speed of 80 km/h, and from B at 45 min later the motorcycle is started at an average speed of 120 km/h. How long will they meet and at what distance from the point A it will be?

Result

t = 8:27 h Wrong answer
s =  116 km

Solution:

 200=80 (T7.00)+120 (T7.0045/60)  12000T=101400  T=16920=8.45  t=T=8.45=16920=8:27 h
s=80 (T7.00)=80 (8.457.00)=116 km
