What are alternate exterior angles?

Step-by-step explanation:

Alternate exterior angles there are two nonadjacent angles formed by two lines and a transversal such that the two angles lie on opposite sides of the transversal and are not between the two lines.

Here it is a picture of alternate exterior angles:

1/5^2 = 7.56/45

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.
