Question 870635: Car A left Melbourne at 11.00 am at an average speed of 70 km per hour.
Car B left Melbourne at 1.00 pm on the same day at an average speed of 90 km per hour.
At what time will Car B catch Car A

Car A 70 mph
Car B 90 mph
Car A 11:00
Car B 01:00
Difference in time= 14:00 => 2.00 hours
Car A will have covered 140.00 miles when Car B starts
catch up distance= 140.00 miles
catch up speed = 90 -70
catch up speed = 20 mph
Catchup time = catchup distance/catch up speed
catch up time=140/7= 7
catch up time= 7.00 hours
They will meet at 08:00 pm
