A fire truck parks 25 feet away from a building. The fire truck extends its ladder 65 feet. How far up the building from the truck's roof does the extension ladder reach?

60 ft

Step-by-step explanation:

An image based on the information provided can be seen in the picture that is attached below. We can calculate the height (b) by using the pythagorean theorem, which is and solving for one of the sides.

625 + = 4225  ..... subtract 625 from both sides

= 3600   ..... square root both sides

b = 60 ft

Finally, we can see that the ladder reaches a total of 60 ft. up the wall.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
