Answer:
"Susanna starts out slower than Anita but still wins the race."
Step-by-step explanation:
The distance of the race is "5 miles". We can see the "endpoint" of each race's graph and corresponding y value. That is 5 miles.
Now, we look at corresponding "x" value, that is the time it took.
For Susannah, it is 5.5 minutes
For Anita, it is 7 minutes.
So, clearly, Susanna wins the race.
Now, we look at the "slopiness" of each person's line graph. This is the speed at which they were going.
The red line (Susanna) is quite sharper than anita, so her speed (rate) is more. But initially, we can see that the blue line (Anita) was sharper than Susanna but later gradually fell. So we can say:
Susanna started out slower than Anita, but ultimately won.
From the answer choices, last one is right -- "Susanna starts out slower than Anita but still wins the race."
Answer: The distance between them is 230.65 miles.
Step-by-step explanation:
Since we have given that
Speed of plane A (b) = 200 miles per hour
Speed of plane B (c) = 300 miles per hour
Angle between them = 50°
So,
We will use the "Cosine formula", we get
So, distance between the two planes after one hour will be
So, the distance between them is 230.65 miles.
(14+19+x)/3=17
x= 18
the first is the equation and the second it the answer
