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.
Speed is defined as the distance covered per time, The formula is given as:
Distance( in kilometers) / Time (in minutes)
They did not run at the same speed.
Step 1: Solving for Andre's speed
2 kilometers/ 15 minutes
= 0.133 kilometers/ minute
This means every minute, Andre ran 0.133 kilometers
Step 2: Solving for Jada's speed
3 kilometers/ 20 minutes
= 0.15 kilometers/ minute
This means every minute, Jada ran 0.15 kilometers
From the above calculation, we can see that they did not run at the same speed.
This is because Jada ran 0.15 kilometers every minute which is faster than Andre who ran 0.133 km every minute.
