Answer 2

Answer: 4 hrs

Distance in first case= 28 km

Time in first case = 2 hrs

Speed in first case = Distance/Time

                                 = 28/2

                                 = 14 km/hrs

Since speed in the first case is equal to the speed in the second case and since the distance covered in the second case is given, we can use it to find the time taken.

Distance in second case = 56 km

Speed in the second case = 14 km/hrs

Time in the second case = ?

We know that,

Speed = Distance/time

So, we can bring time to the other side

Speed x Time = Distance

Now we can bring speed to the other side

Time = Distance/Speed

Now we can substitute the values

Time = Distance/Speed

Time = 56/14

        = 28/7

       = 4 Hours

Therefore the time will be 4 hours so option C is correct.
