The paul one thanks.

p-5 = 66

p = 71

Step-by-step explanation:

The first equation says that his current age-5 =66, which is the same thing as saying that he was 66 5 years ago.

The second equation was achieved by adding 5 to both sides of the first equation

Equation: Paul (p) - 5 = 66,

p = 66 + 5.

solve: p = 71.

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.
