The Distance cover by boat in 2 hours and 15 minutes is 72 km
Step-by-step explanation:
Given as :
The Distance cover by boat = 128 kilometer
The time taken is 4 hours
As , Distance = Speed ×Time
So , Speed =
Or, Speed =
∴ Speed = 32 km per hour
Now, again The boat travel 2 hours and 15 minutes further with speed 32 kmph
So, Time2 = 2 +
Or, Time2 = 2 +
I.e Time2 = hours
Again , Distance = Speed ×Time
So , Distance = 32kmph × hours
I.e Distance = = 72 kilometer
Hence The Distance cover by boat in 2 hours and 15 minutes is 72 km Answer
