Growth meters per second = 4.8 ×

First, you need to convert standard form into a normal number.
4.8 ×

= 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 ×

(standard form)
b) 365 days in a year, so multiply 4.800000000 and 365
4.800000000 × 365 = 1752 = 1.7 ×

(standard form)

Answer:
b ≈ 148.5
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan68° =
= 
Multiply both sides by 60 to clear the fraction
60 × tan68° = b, thus
b ≈ 148.5 ( to 1 dec. place )
