Motion

From two different locations distant 232 km started against car and bus. The car started at 5:20 with average speed 64 km/h. Bus started at 7:30 with average speed 80 km/h.

When they meet?
How many kilometers went the bus?

Result

x (hh:mm) = 8:09 Wrong answer
s2 =  51.9 km

Solution:

 Δt=(75)+160(3020)=2.17 h  s1+s2=232 v1(t+Δt)+v2t=232  t=23264Δt64+80=0.65 h x=5+16020+t+Δt=8.153 x=8:09
s2=v2t=800.65=51.9 km
