Answer:

A

Step-by-step explanation:

The easiest way to do this problem is to find out how far he can go in 1/2 hour.

If he goes 3 miles in 1 hour

he will go 3/2 miles in 1/2 hour

=============

Now just add this onto the distance travelled in 1 hour.

3 + 3/2 = 3 + 1.5 = 4.5

The answer is A

The answer can be obtained another (perhaps better ) way.

Set up a proportion

1 hour gives 3 miles

1.5 hours gives x

1/1.5 = 3/x                Cross multiply

1*x = 1.5 * 3             Combine    

x = 4.5 miles

GIVING BRAINLIEST WHOEVER ANSWER THIS CORRECT THANK U.
Sonja [21]

Answer:

The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)

Step-by-step explanation:

Translations

A given point A(x,y) when translated by the rule (h,k) maps to A'(x+h,y+k).

We are given the point X(3,-2) and its image at X'(2,-4). The rule for the translation used is:

(h,k)=(2,-4)-(3,-2)=(2-3,-4+2)=(-1,-2)

If we apply the same translation to the point Y(7,1) we get the image Y'(7-1,1-2)=Y'(6,-1).

If we apply the same translation to the point Z(-1,2) we get the image Z'(-1-1,2-2)=Z'(-2,0).

The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)

it's a example from another eqaqthion
