Question

29. Distance between two places A and B is 350 km. Two cars start simultaneously from
A and B towards each other and the distance between them after 4 hours is 62 km. If
speed of one car is 8 km/h less than the speed of other car, find the speed of each car.
​

Answer 1

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
