Sagot :
Answer:
(x + 2 x) * t = 300 km
3x = 300 km/ 2 hrs = 150 km / hr
x = 50 km / hr
One car traveled at 50 km / hr and the other at 100 km / hr
In 2 hours they traveled 300 km
The speed of the first car is 100 km/hr and that of the second car is 50 km/hr.
What are work and time?
Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour. In essence, work is the length of time it took you to complete any task.
Speed of the second car is = v
The speed of the first car = 2v
Given that
Distance covered by = 300 km
Time taken = 2 hr
By relative velocity concept
2v + v = 300/2
3v = 150
v = 50 km/hr.
Hence the speed of the first car will be 100 km/hr and that of the second car will be 50 km/hr.
