Answer:
She saw 60 dogs over the two days.
Step-by-step explanation:
Consider the provided information.
It is given that Maria saw dogs in the park on Saturday.
can be written as 2×10 = 20
That means she saw 20 dogs on Saturday.
She saw twice as many dogs on Sunday as she saw on Saturday.
She saw 20 dogs on Saturday the twice of this is:
Sunday = 20×2 = 40 dogs
Total number of dogs she saw on Saturday and Sunday = 40 + 20 = 60
Hence, she saw 60 dogs over the two days.

Answer:
Distance from the airport = 894.43 km
Step-by-step explanation:
Displacement and Velocity
The velocity of an object assumed as constant in time can be computed as
Where is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as
The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as
The displacement of the plane in 2 hours is
Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are
The displacement in 1 hour is
The total displacement is the vector sum of both
The distance from the airport is the module of the displacement:
There can be no negative in a sqrt
