Determine 21903

A truck left place A at 8:00 a.m. at a speed of 60 km/h. From place B, which is 225 km from A, a car drove towards it at a speed of 90 km. Determine when and how far from place A the vehicles meet.


t = 9:30 hh:mm Wrong answer
s1 =  90 km

Step-by-step explanation:

s1+s2=s v1=60 km/h v2=90 km/h s=225 km  v1 (x8.00)+v2 (x8.00)=s 60 (x8.00)+90 (x8.00)=225  150x=1425  x=1501425=9.5  x=219=9.5  t=x=9.5=9:30 hh:mm
s1=v1 (x8.00)=60 (9.58.00)=90 km
