The perimeter of a triangle is 74 cm. the longest side is 10 cm less than the sum of the other two sides. twice the shortest side is 2 cm less than the longest side. find the length of each side of the triangle shortest side : ? middle side : ? longest side : ?

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.
