the relative answer
The speed of car 1 is 40 km/hr.
The speed of car 2 is 45 km/hr.
Step-by-step explanation:
Given : Two cars leave Delhi from a point at the same time, travelling in the opposite direction. If the average speed of one car is 5 km/hr more than that of the other and they are 425 km apart at the end of 5 hours.
To find : What are the average speeds of the two car?
Solution :
Let the speed of car 1 = x km/h
The speed of car 2 = x+5 km/h
They are moving away from each other
Combined speed = x+x+5=2x+5 km/h
Time = 5 hours
Distance = 425 km
\text{Distance} = \text{Speed}\times \text{Time}Distance=Speed×Time
425= 2x+5\times 5425=2x+5×5
425= 10x+25425=10x+25
10x=425-2510x=425−25
10x=40010x=400
x=\frac{400}{10}x=10400
x=40x=40
The speed of car 1 is 40 km/hr.
The speed of car 2 is 40+5=45 km/hr.
