Answer: (b) 138 min

Solution:-
Juhi traveled a distance of 16 km by bicycle at the speed of 15 km per hour.
Then, time taken by Juhi = 16 x 60/15
= 16 x 4
= 64 min

She travel 20 km by scooter at the speed of 50 km per hour,
Then, Time taken by her to travel 20 km = 20 x 60/50
= 24 min

She travel 50 km by the car at the speed of 60 km per hour,
Then, time taken by her to travel 50 km = 50 x 60 /60
= 50 mjn

Total time taken by Juhi to travel whole journey = 64 + 24 + 50
= 138 min

Hence, the correct answer is option (b) 138 min.
