Question

two cars leave Delhi at the same time travelling in opposite direction if the average speed of one car is 5 km per hour than that of the other and they are 425km apart at the end of 5 hours what is the average speed of each​

Answer 1

Answer:

Step-by-step explanation:

Let speed of car1 be= x

Therefore speed of car2 = x+5

Distance travelled in 5 hrs:

Car1= 5x

Car2= 5(x+5)

Distance between cars after 5 hrs= 425km

Equation:

5x+ 5(x+5)= 425

5x+ 5x+ 25= 425

10x= 425-25

10x= 400

x= 400/10

x= 40km/hr

Speed of car1= 40km/hr

Speed of car2= 45km/hr
