Answer:

unit rate = 2.57 blocks / min

Time = 19.444 ...

Step-by-step explanation:

The unit rate is how far she can travel in 1 minute.

Rate is defined as distance / time

Givens

distance = 18 blocks

time = 7 minutes

Solution

rate(r) = distance(d) / time(t)

r = 18 blocks / 7 minutes

r = 2.57143 blocks / minute

==========

Set up the ratio for 50 blocks

1 minute / 2.57143 blocks = x / 50 blocks    Multiply both sides by 50

1 * 50 / 2.57143 = x * 50 / 50

x = 50 / 2.57143

x = 19.4444...

2. HL can be a reason to show given triangles are congruent as the triangles are right triangle with equal legs and hypotenuse.

3. SAS can be a reason to show given triangles are congruent as there are  two congruent sides in both triangles and included angles ∠A=∠D=90° [right angle].

4. LA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.

5. AAS  cannot be a reason to show given triangles are congruent as it is not given that they have two angles common in both the triangles.
