A bus travels at 100km/h for the first 1/2 hour. Later it travels at 80km/h. Find the time taken by the bus to travel 290 km.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3.5 hours
A bus travels at 100km/h for the first 1/2 hour
The distance covered in 1/2 hour = 100 * (1/2) = 50 km
The remaining distance = 290 - 50 = 240 km
Speed = 80km/h
Time taken = 240/80 = 3 hours
Hence, the total time taken by bus to cover 290 km = 3 + 0.5 = 3.5 hours
