4-11/3 = 1/3 km/hr speed reduced it takes 3 hr extra
3×1/3 km/hr speed reduced it will take 3×3=9hr extra
4 km/hr speed reduced ..it will take 9×4=36 hr
now the distance = speed × time = 4×36 = 144 km/hr
3×1/3 km/hr speed reduced it will take 3×3=9hr extra
4 km/hr speed reduced ..it will take 9×4=36 hr
now the distance = speed × time = 4×36 = 144 km/hr
