When converting from a smaller to a larger unit of measurement, you move the to the right. a. second number b. ratio c. exponent d. decimal point

The correct answer is D. decimal point.

Explanation:

The question is wrong. It should be :

When converting from a smaller to a larger unit of measurement, you move the _______ to the left.

In order to convert from a smaller to a larger unit of measurement what we need to move is the decimal point to the left. Let's see an example :

We have the two following units

'''' which is grams and '''' which is kilograms.  

We know that the grams are a smaller unit of measurement that kilograms.

We also know the relationship :

For example if we want to convert to kilograms :

What we have done is that we divided the number ''1500'' by ''1000''.

This is equal to move the decimal point three places to the left ⇒

The correct answer is D. decimal point

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
