Distance covered in 12 minutes at 50 km/hr =50 x (12/60) Distance covered in 10 minutes at (50 + x) km/hr = (10/60) x (50 + x) Now, Distance covered in 12 minutes at 50 km/hr = Distance covered in 10 minutes at (50 + x) km/hr ⇒ 50 x (12/60) = (10/60) x (50 + x) ⇒ 50 x 12 = 500 + 10x ⇒ 600 = 500 + 10x ⇒ 10x = 600 - 500 = 100 ⇒ x = 10 km/hr
