Answer 2

Solution :-

Time = 20 minutes(mins)

Distance=15 kilometres(km)

We have to convert minutes into hour,to find speed in km/h;

---------->         60 mins=1 hour

                      20 mins=1/60*20 hour

                                    = 1/3 hour

 

         Speed=Distance/time

                     = 15/(1/3)

                     = 45 km/h

Answer :- 45 km/h  is the answer.
