★Given :
→ Speed = 54 km/hr
→Time = 50 min
_____________________________
★To Find :
→Time to cover distance 30 km / hr ?
_____________________________
★ Explanation :
⇒ At first we need to convert 3 hours 20 minutes into minutes
i.e. 3×60+20 = 200 minutes
Now simply use the formula of time and distance
☛ Distance = speed × time
∴ Speed = 54 km per hour i.e. 54 km in 60 minutes
Or in 1 minute 54/ 60 ( as we converted the unit in minutes )
⇒Time = 200 minutes
∴ Now Distance = 54/60 × 200
= 9× 20 = 180 km
( cancelled out a single zero from 60 and 200 and dividing 54 by 6)
⇒Ans: It will cover 180 km in 3 hours and 20 minutes.
