The table given here represents the distance (in km) travelled by two athletes X and Y in the same direction.
| Distance Travelled (in Km) | ||
| Hour | X | Y |
| 1st | 25 | 30 |
| 2nd | 35 | 45 |
| 3rd | 25 | 40 |
| 4th | 20 | 30 |
| 5th | 25 | 20 |
| 6th | 20 | 15 |
Y’s average speed (km/hour) during the first five hours is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 33.
Average speed = Total distance/Total time
Total distance travelled by Y during the first five hour = 30 + 45 + 40 + 30 + 20 = 165 km
Total time taken = 5 hour
Average speed = 165/5 = 33 km/hour
