Distance covered in 15 minutes at 60 km/hr =60 x (15/60) Distance covered in 12 minutes at (60 + x) km/hr = (12/60) x (60 + x) Now, Distance covered in 15 minutes at 60 km/hr = Distance covered in 12 minutes at (60 + x) km/hr ⇒ 60 x (15/60) = (12/60) x (60 + x) ⇒ 60 x 15 = 720 + 12x ⇒ 900 = 720 + 12x ⇒ 12x = 900 - 720 = 180 ⇒ x = 15 km/hr
