Direction: The following questions are based on the table given below which represents the distance (in km) travelled by two persons A and B in the same direction :
-
The ratio of A’s speed during the first five hours and the last five hours is
-
- 25 : 22
- 22 : 25
- 15 : 22
- 20 : 21
Correct Option: B
From the given above table ,
Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
Total time taken = 5 hours
Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
Total time taken = 5 hours
| Required ratio = | : | Total time taken | Total time taken |
| Required ratio of average speed = | : | = 110 : 125 = 22 : 25 | 5 | 5 |
