What's the pattern of 40, 10, 5/2, 5/8

The sequence is starting at 40, then 10, then 5/2...so on.

It has a common ratio of 1/4.

So the pattern is multiplying each number by 1/4

40 x1/4 = 10

10 x 1/4 = 5/2

5/2 x 1/4 = 5/8

next should be 5/8 x 1/4 = 5/32

step-by-step explanation:

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.
