9 hours long after the second runner started will the second runner overtake the first runner.

What does it mean to do speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
Put another way, speed is a scalar value, while velocity is a vector.

Runner I = 6 mph

Runner II = 7 mph

Difference in time= 90 minutes

Train A will have covered 9 miles before Runner II starts

catch up distance= 9 miles

catch up speed = 7-6 mph

catch up speed = 1 mph

Catchup time = catchup distance/catch up speed

catch up time= 9/1

catch up time= 9 hours
