The average speed of the family during their walk will be 1.4 km per hour.
<h3>What is the average speed?</h3>
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. Its unit is a meter per second or Km per hour.
Given that over a 1.35-hour period of time, a family walk 0.75 km, stop to talk to the neighbor, and then walk another 1.15 km before reaching their destination.
The average speed will be calculated as:-
Average speed = Total distance / Total time
Average speed = ( 1.15 + 0.75 ) / 1.25
Average speed = 1.4 km per hour.
Therefore, the average speed of the family during their walk will be 1.4 km per hour.

Answer:
<u>The best estimation of the fraction of the batch that was left is 5/84</u>
Step-by-step explanation:
Mr. Gallegos has:
A batch of muffins = 1
He gave 11/21 of the batch to his neighbors:
1 - 11/21 = 21/21 - 11/21 = 10/21
He ate 1/8 of the batch himself:
10/21 - 1/8 = 10/168
= 10/168 (dividing by 2)
= 5/84
<u>The best estimation of the fraction of the batch that was left is 5/84</u>
The length of the lighthouse (120) and the length of the shadow (160) form the sides of a triangle.
Use the formula a^2 + b^2 = c^2
120^2 + 160^2 = c^2
