Excluding stoppages, the speed of an inter-city bus is 45 km/h and including stoppages it is 36 km/h. How many minutes does the bus stop per hour? MCQ with Answer and Explanation

Explanation:
By 6:00 AM, the thief has traveled for 1 hour and covered 40 km. Relative speed = 50 - 40 = 10 km/h. Time taken to catch = 40 / 10 = 4 hours. Capture time = 6:00 AM + 4 hours = 10:00 AM.

Explanation:
Time = 1 minute 40 seconds = 100 seconds. Speed = 5000 / 100 = 50 m/s. In km/h = 50 * (18/5) = 180 km/h.

Explanation:
Time taken to cross the bridge alone = 15 - 9 = 6 seconds. Speed of train = 150 / 6 = 25 m/s. Length of train = Speed * Time to cross sign post = 25 * 9 = 225 meters.
