Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.

Answer:
Understanding basic business math is necessary for profitable operations and accurate record keeping. Knowing how to add, subtract, multiply, divide, round and use percentages and fractions is the minimum you need to price your product and meet your budget.
No triangle formed
Solution:
Given data:
One angle is 45°
Another angle is 108°
One side is 7 cm
To find how many triangles are formed for the given data.
Let the unknown side of a triangle be x°.
Sum of all the sides of a triangle = 180°
45° + 108° + x° = 180°
⇒ x° = 180° – 45° – 108°
⇒ x° = 27°
There is no such angle can be formed with 27° in the given image.
Hence there is no triangle can be formed.
