Answer:
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 = [tex]\frac{Diastance}{Time}[/tex]
Or, Speed = [tex]\frac{128 km}{4 hours}[/tex]
∴ Speed = 32 km per hour
Now, again The boat travel 2 hours and 15 minutes further with speed 32 kmph
So, Time2 = 2 + [tex]\frac{15}{60}[/tex]
Or, Time2 = 2 + [tex]\frac{1}{4}[/tex]
I.e Time2 = [tex]\frac{9}{4}[/tex] hours
Again , Distance = Speed ×Time
So , Distance = 32kmph × [tex]\frac{9}{4}[/tex] hours
I.e Distance = [tex](\frac{32\times 9}{4})[/tex] = 72 kilometer
Hence The Distance cover by boat in 2 hours and 15 minutes is 72 km Answer
