two cars leave Minglanilla and travel in opposite direction. one of the cars average is 12 km/hrs less than the other. after 3 hours they are 396 km. apart. what is the average speed of each car?

Sagot :

Nikki1996viz
car A = 72 km/ hr
car B = 60 km / hr
Jers15viz
First Car=x
Second car=x-12

3x+3(x-12)=396
3x+3x-36=396
6x=432
x=72

The first car travels 72kmph and the second car travels 60kmph

Hope this helps =)
