Joshua likes to read he read 6 books when he was 6 years old every year he doubled the number of book he read the previous year how many total books did he read between the ages of 6 and 10?

Joshua read 186 books form 6 to 10 years of age.

Step-by-step explanation:

Joshua reads 6 books at the age of 6.

He doubled the number of books he read the previous years.

Now the sequence will be a geometric sequence as

6, 12, 24, ......

We have to calculate the number of books he read from 6 years to 10 years of his age.

Since sum of n terms of a geometric sequence is given by

where a = first term

r = common ratio

n = number of terms

   =

   = 6×31

   = 186 books

Therefore Joshua read 186 books form 6 to 10 years of age.

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.
