suppose speed is X kmph, so distance covered in 7 hours is equal to 7X kms. now speed is increased to 12 kmph, and same distance is covered in 5 hours so total distance covered is equal to (X+12)5 kms.
so 7X= (X+12)*5
or X= 30
so distance travelled is 7* 30= 210kms.

RE: Distance travelled

Increased speed by 12Km/hr?
or Increased speed to 12Km/hr?

If first, none. If second, it takes 5 hours to return with 12Km/hr. So, 5 multiply 12 equals 60 Km. Since it is round trip, it is going to be 120 km.
