solution:

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
