Answer 1

Hi.

Here is your answer---

____________________________

Given---
   Speed = 50 2/5 km/hr.
              = 252/5 km/hr    [ Converting into simple Faction]
              = (252/5) × 5/18 [ Converting into m/s.]
              = 14 m/s.

Distance = 200 km + 100 m
               = 200000m  + 100 m
               =  200100 m

Using the Formula,
   Speed = Distance/Time

 Time = Distance/Speed
          = 200100/14
          = 14292.86 seconds.
