Answer:


Step-by-step explanation:

given that

630 km = 9 hours

to find - rest speed

so , 2/3 of journey = 630 x 2/3 = 420 km

time taken = 420/60

                   =7 hours

distance left = 630 - 420

                     = 210 km

time left = 9 hours - 7 hours

              = 2 hours

speed in rest time = 210 / 2 hours

                               = 105 km per hour
