Growth meters per second = 4.8 × $10^{-9}$

First, you need to convert standard form into a normal number.

4.8 × $10^{-9}$ = 4.800000000

a) In one day there are 24 hours, therefore you will multiplying 4.800000000 and 24

4.800000000 × 24 = 115.2  = 115.2 × $10^{-9}$ (standard form)

b) 365 days in a year, so multiply 4.800000000 and 365

4.800000000 × 365 = 1752 = 1.7 × $10^{3}$ (standard form)

Hope I helped (:

have a great day!
