Given, Speed $= 50$ km/hr $= 50 / 60 = 5 / 6$ km/min
Time taken by bus to cover distance $= 48$ min
Distance $= s p e e d \times t i m e = 48 \times \frac{5}{6} = 40$ km

$∴$ Time it will take to cover $40$ km at $30$ km/h
= distance / speed $= 40 / 30$ = $\frac{4}{3} h r s = 4 \times 20$ min
= $80$ minutes.
