Answer:
46.7
Step-by-step explanation:
3 × 50 = 150 miles
60 ÷ 40 = 1.5 h.
(150 + 60) ÷ (1.5 + 3) = 46.7 mph
(Speed × Time = Distance)
A generalization is a broad statement or an idea that is applied to a group of people or things. Most o<span>ften, generalizations are not entirely true, because usually, the pattern they see in the relationship of a certain group of individuals or situations does not apply. In our example, where Elisa, Sandy, and Jared got sick and were absent from school for two days straight, within the 3 week period, we can make the following generalizations patterns:</span>
<span>1) </span>There is an outbreak of sickness in the school for 3 consecutive weeks.
<span>2) </span><span>The said sickness lasts for two days.</span>
