Step-by-step explanation:
Given
Distance between two places A and B =350km
Let the speed of car C1=xkm/h and
Speed of car C2=(x−8)km/h
After 4 hours , the distance between two cars is 62km
Hence ,
x×4+(x−8)×4=350−62
4x+4x−32=288
8x=288+32
8x=320
x=8320
We get ,
x=40
Therefore , speed of car C1=40km/h
Speed of car C2=(x−8)=(40−8)=32km/h
