Final answer:

The car travels 100 feet in 0.5 seconds, equating to 200 feet per second. Multiplying this by the 60 seconds in a minute gives us 12,000 feet, making option B the correct answer.

Step-by-step explanation:

The correct answer is option B. 12,000 feet. To find out how many feet the race car will travel in a minute, we first need to determine the car's speed in feet per second (ft/s). Since the car travels 100 feet in 0.5 seconds, we double this amount to find its speed per second, which is 200 feet per second. There are 60 seconds in a minute, so we then multiply the car's speed by the number of seconds in a minute:


(200 ft/s) × (60 s) = 12,000 feet.

Hence, at this rate of speed, the race car will travel 12,000 feet in one minute.

To find how many feet the race car will travel in a minute, we need to calculate the number of 0.5-second intervals in a minute and multiply it by the distance travelled in one interval.

In one minute, there are 60 seconds. Since each interval is 0.5 seconds, we can divide 60 by 0.5 to find the number of intervals in a minute: 60 / 0.5 = 120 intervals.

Since the race car travels 100 feet in one interval, we can multiply the number of intervals by the distance travelled in one interval: 120 intervals * 100 feet = 12,000 feet. So, the race car will travel 12,000 feet in a minute.

Answer: Is D 12,000 feet

Step-by-step explanation:

o find out how many feet the race car will travel in a minute, first, determine the speed in feet per second. The speed is calculated by dividing the distance traveled by the time taken:

Speed

=

Distance

Time

Speed=

Time

Distance

In this case, the distance is 100 feet, and the time is 0.5 seconds:

Speed

=

100

feet

0.5

seconds

=

200

feet/second

Speed=

0.5 seconds

100 feet

=200 feet/second

Now, to find the distance traveled in a minute (60 seconds), multiply the speed by the time:

Distance

=

Speed

×

Time

Distance=Speed×Time

Distance

=

200

feet/second

×

60

seconds

Distance=200 feet/second×60 seconds

Distance

=

12

,

000

feet

Distance=12,000 feet

Therefore, the race car will travel 12,000 feet in a minute.

Among the provided options, the correct one is:

D. 12,000 feet
