Answer:

The average speed of the boat is 20 km/hr.

Step-by-step explanation:

Given : A boat that moves 15.0 km across a lake in 45 min.

To find : What was the average speed in km/h ?

Solution :

The distance a boat covered is 15 km.

The time taken by boat to cross a lake is 45 minutes.

Convert minute into hour,

1 hour = 60 minute

1 minute = \frac{1}{60} hour

45 minute = \frac{45}{60} hour

45 minute = 0.75 hour

The speed of the boat is given by,

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

\text{Speed}=\frac{15}{0.75}

\text{Speed}=20

The average speed of the boat is 20 km/hr.
