Calculate Ana's Time to Catch Carla in Athletics Competition

Question:

If Carla's speed is 20% less than Ana's speed, and Carla has a head start of 5 seconds in a running competition, how long will it take for Ana to catch up to Carla in meters?

Answer:

We can see here that the correct answer is: D) 30 - 240.

Explanation:

To solve this problem, we first need to calculate Carla's speed and then determine how long it will take for Ana to catch up to her.

Calculating Carla's Speed:

Carla's speed is calculated as distance divided by time. For Carla:

Speed of Carla = Distance / Time

Speed of Carla = 300 m / 25 s

Speed of Carla = 12 m/s

Now we know that Carla's speed is 12 meters per second.

Calculating Ana's Time:

Since Ana has a head start of 5 seconds, her time will be Carla's time plus 5 seconds:

Time of Ana = Time of Carla + 5 s

Time of Ana = 25 s + 5 s

Time of Ana = 30 seconds

Now, we need to determine the distance Ana will cover in 30 seconds to catch up to Carla. Given that Ana's speed is 20% greater than Carla's, we can calculate her speed:

Speed of Ana = 1.20 x Speed of Carla

Speed of Ana = 1.20 x 12 m/s

Speed of Ana = 14.4 m/s

Using the distance formula, we can calculate the distance Ana will cover in 30 seconds:

Distance = Speed x Time

Distance = 14.4 m/s x 30 s

Distance = 432 meters

Therefore, Ana will cover 432 meters in 30 seconds to catch up to Carla.
