Two cars starts from the same place at the same time but in opposite directions.Their speeds are 80km/hr and 65km/hr. After how long they be 580 km apart?

Dear Student,

Distance travelled by 1st car in 1 hour = speed×time = 80 kmDistance travelled by 2nd car in 1 hour = speed×time = 65 kmTotal distance travelled in 1 hour = 80+65 = 145 kmTime taken to cover 580 km = 580145 = 4 hours So, after 4 hours they will be 580 km apart.

Regards
