Practicing Success
Two trains P and Q start from stations S and T towards each other. Train P takes 4 hours 48 minutes and train Q takes 3 hours 20 minutes to reach T and S, respectively, after they meet. If the speed of train P is 45 km/h, what is the speed of train Q ? |
48 km/h 50 km/h 54 km/h 55 km/h |
54 km/h |
Formula used :- (\(\frac{Speed \;of \;train\; P}{Speed\; of\; train\; Q}\))^2 = \(\frac{After \;meeting \;each \;other\; time \;taken\; by \;train\; Q}{After \;meeting \;each \;other\; time \;taken\; by \;train\; P}\) 4 hours 48 minutes = \(\frac{24}{5}\) hours |
