and multiply that by 31 which is 21.7 km and for the 14 min it’s 14/60 times 27 which is 6.3 adding up all the kilometers gives you 32.1+21.7+6.3 and then you add all the minutes 26+40+14+12 which is 92 divide that by 60 and you get 1.53 hours and the km are 60.1, 60.1/1.53 gives us 39.3km/h.

of the car?
TE 10m
Answers
The centripetal acceleration of the car is equal to [tex]22.5 \;m/s^2[/tex].
Given the following data:
Radius, r = 10 meterSpeed, V = 15 m/s.To determine the centripetal acceleration of the car:
Mathematically, the centripetal acceleration of an object is given by the formula:
[tex]A_c = \frac{V^2}{r}[/tex]
Where:
[tex]A_c[/tex] is the centripetal acceleration.r is the radius of the circular track.V is the velocity of an object.Substituting the given parameters into the formula, we have;
[tex]A_c = \frac{15^2}{10}\\\\A_c = \frac{225}{10}\\\\A_c = 22.5 \;m/s^2[/tex]

A taxi drives 300.0 m south and then turns and drives 180.0 m east. What is the total displacement of the taxi?
Answers
Please find attached photograph for your answer.
Hope it helps.
Do comment if you have any query.
The total displacement of the taxi is approximately 349.68 m.
To find the total displacement of the taxi, we can use the Pythagorean theorem since the south and east directions form a right triangle.
Given:
Distance traveled south = 300.0 m
Distance traveled east = 180.0 m
Treat the south direction as the negative y-direction and the east direction as the positive x-direction.
Using the Pythagorean theorem, the total displacement (D) is given by:
D = √((Δx)² + (Δy)²)
Where:
Δx is the change in the x-direction (east)
Δy is the change in the y-direction (south)
Let's calculate the total displacement:
Δx = 180.0 m (east)
Δy = -300.0 m (south)
D = √((180.0 m)² + (-300.0 m)²)
D = √(32400.0 m² + 90000.0 m²)
D = √(122400.0 m²)
D ≈ 349.68 m
Therefore, the total displacement of the taxi is approximately 349.68 m.

Otto is a football player and he is working on getting in shape but carbohydrates fuel the body, so this is not the best idea. Hence, option C is correct.
What is diet?Diet, as used in nutrition, refers to the items a person frequently eats and drinks (or a group). A regulated diet, or one that fulfills the physical needs of an individual, may be used during a specific illness therapy or health condition management.
For instance, a diabetic's diet could be limited to a few foods and beverages that can assist control blood sugar levels. Diabetes patients are advised to consume a lot of fiber, non-starchy fruits, and vegetables. Because starchy foods are high in carbohydrates, eating a lot of them may raise your blood sugar levels.
According to the question, otto is working out several times a day so he needs energy which is provided by a carb diet that contains carbohydrates. So, he must take some carbs on a regular basis.
