Excluding stoppages, the speed of a bus is 50 km/h and including stoppages it is 40 km/h. For how many minutes does the bus stop per hour? MCQ with Answer and Explanation
Two cars start from the same spot and travel along perpendicular roads. One travels at 15 km/h and the other at 20 km/h. Find the distance between them after 2 hours.
Explanation:
In 2 hours, the first car travels 30 km and the second car travels 40 km. Direct distance = sqrt(30^2 + 40^2) = sqrt(900 + 1600) = sqrt(2500) = 50 km.
