Answer:
Distance Vivek traveled = 1729 km
Time taken to travel = 19/2 hrs
Speed in which he traveled = speed=distance/time
= 1729/ 19/2= 1729×2/19 = 182 km/hr
(a) Time taken = 13/2
Speed = 182 km/hr
Distance he traveled= distance=speed×time
182× 13/2 = 1183 km
(b) Distance he traveled = 12831/50 km
Speed = 182 km
Time taken to travel = time=distance/speed
=12831/50 / 182= 12831/50 × 1/182 = 141/100hrs
= 1.41hrs
