Direction: Study the data carefully and answer the question given beside:
The table shows the distance travelled by five different boats upstream and downstream in same time and the line chart shows the speed of stream
The speed of Boat Q and S in still water together is approximately how much percentage more than the speed of stream of the same boats together?
Explanation:
According to the question,
Speed of Boat Q and S in still water together = (25 + 24) = 49 km/h
Speed of stream of Boat Q and S together = 18 km/h
| % more = |
49 – 18 |
× 100 |
| 18 |
| = |
31 |
× 100 = 172.22% ≈ 170% |
| 18 |
Hence, option C is correct.
