Anand covers a distance of 20 km at the speed of 4 km/h and he covers remaining distance at the speed of 5 km/h in 5 hours. What is the average speed (in km/h) of Anand for the whole journey?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4.5
Time taken by Anand to cover 20km = 20/4 = 5 hours
Remaining distance covered at 5km/h = 5 × 5 = 25 km
Average speed = (Total distance covered by Anand)/(Total time taken by Anand) = (25 + 20)/(5 + 5) = 45/10 = 4.5 km/hr
