Question

Brenda has two remote-controlled race cars painted blue and red, respectively.The blue car traveled 54 feet 4 secounds.The red car traveled 38 feet im 2 seconds.

Answer 1

The question is about calculating the speeds of two remote-controlled race cars by dividing the distance traveled by each car by the time taken. The blue car travels at 13.5 feet per second, while the red car travels at 19 feet per second. The red car is faster.

Step-by-step explanation:

The question involves calculating the speed of two remote-controlled race cars, which is a mathematical problem typical for Middle School students. To find the speed, you divide the distance traveled by the time it took to travel that distance.

For the blue car:

Speed = Distance ÷ Time = 54 feet ÷ 4 seconds = 13.5 feet per second.

For the red car:

Speed = Distance ÷ Time = 38 feet ÷ 2 seconds = 19 feet per second.

Therefore, we can see that the red car has a higher speed compared to the blue car.

Answer 2

The red car is faster compared to the blue car.

The red car is faster by 5.5 feet than the blue car.

Step-by-step explanation:

The objective is to find which car is faster and by how much

Given that:

The blue car traveled 54 feet in 4 seconds; &

The red car traveled 38 feet in 2 seconds.

Let us determine the number of feet traveled in each second for both cases.

For the blue car:

In 1 second, the car will travel = 54/4 feet

In 1 second, the car will travel = 13.5 feet

For the red car:

In 1 second, the car will travel = 38/2 feet

In 1 second, the car will travel = 19 feet

Thus, the red car is faster compared to the blue car.

The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet

= 5.5 feet
