Total time is
Average speed for no current is
Explanation of Solution
Given:
A moto boat travel at
The boat makes
Concept used:
Average speed=
Calculation:
The speed in still water is
Use the information to fill the tables:
With no current:
rate | time | distance | |
Down stream | |||
Up stream |
Total distance is then
Total time is then
Average speed=
Now with current
rate | time | distance | |
Down stream | |||
Up stream |
Total distance is then
Total time is then
Average speed=
Hence, with no current and with
Total time is
Average speed for no current is
