Cars

Cars started at 7:00 AM.
From point A, the car runs at 40 km per hour, and from B, the car runs at 70 km per hour. Between A and B is a 250 km long road.

When and where will they meet (measured from point A)?

Result

T = 9:16 hh:mm Wrong answer
s1 =  90.91 km

Step-by-step explanation:

v1=40 km/h v2=70 km/h s=250 km  s1 = v1 t s2 = v2 t  s = s1+s2 = v1 t + v2 t = t(v1+v2)  t=v1+v2s=40+70250=11252.2727 h  T=7+t=7+2.2727=9.27273=9:16 hh:mm
s1=v1 t=40 2.2727=90.91 km
