B. 60 km/h
C. 53 km/h
D. 45 km/h

Answer

C

Explanation

Time for travel on 29th November = (24:00-19:45)= 4:15 h
Time for travel on 30th November = 24 h
Time for travel on 1st December = 11:45 h
Total time taken for travel by express train from Surat to Nagarcoil
= 4:15 + 24:00 +11:45 = 40 h
Total covered distance for travel by express train from Surat to Nagarcoil = 2120 km
`:.` Average speed of train = `("Total covered distance")/("Total time") = (2120)/(40)` = 53 km/h
