A bus covered 630 kms in 9 hours, if it travels at one-seventh of its usual speed. Then how much more time will it take to cover the same distance? |
63 h 61 h 50 h 45 h |
63 h |
S = \(\frac{D}{T}\) S = \(\frac{630}{9}\) = 70 km/h \(\frac{1}{7}\)th of S = 10 km/h New Time = \(\frac{630}{10}\) = 63 h |
