An aeroplane flies at a speed of 7.0 X 10 meters per hour. How long will if take to cover a di​

Answer 1

(1)  5623456 x 108

    = 607333248.0

now to write in scientific notation we have to write it as k x 10^x in which 1<k<10

=> 6.07333248 x 10^x

over hear since we moved the decimal point of 607333248 eight times to the left, x will be 8. Remember that if you move the decimal point to the right, x will be negative and if you move it to the left it will be positive.

∴ 5623456 x 108= 6.07333248 x 10^8

apply this for the rest of this fr the other sums
