In 4 hours, a comet that is far from the sun usually travels 8,000 miles. How far will the comet travel in 10 hours?(1 point)
To find out how far the comet will travel in 10 hours, we need to calculate its speed per hour and then multiply that by the number of hours.
The comet's speed per hour can be found by dividing the distance it travels in 4 hours by 4:
8,000 miles ÷ 4 hours = 2,000 miles per hour
Then, the distance the comet will travel in 10 hours can be found by multiplying its speed per hour by 10:
2,000 miles per hour × 10 hours = <<2000*10=20000>>20,000 miles
Therefore, the comet will travel 20,000 miles in 10 hours.
Brian ran a 5-kilometer race in 40 minutes. How far did he run in 18 minutes? Write your answer as a decimal and do not round.(1 point)
$$
To find out how far Brian ran in 18 minutes, we need to calculate his average speed and then multiply that by the number of minutes.
Brian ran 5 kilometers in 40 minutes, so his average speed is:
5 kilometers ÷ 40 minutes = 0.125 kilometers per minute
Then, to find how far Brian ran in 18 minutes, we can multiply his average speed by 18:
0.125 kilometers per minute × 18 minutes = 2.25 kilometers
Therefore, Brian ran 2.25 kilometers in 18 minutes.
In 3 hours, the Johnson family traveled 195 miles by car. How far will they travel in 5 hours?(1 point)
$$
To find out how far the Johnson family will travel in 5 hours, we need to calculate their average speed per hour and then multiply that by the number of hours.
The Johnson family traveled 195 miles in 3 hours, so their average speed per hour is:
195 miles ÷ 3 hours = 65 miles per hour
Then, to find how far they will travel in 5 hours, we can multiply their average speed by 5:
65 miles per hour × 5 hours = 325 miles
Therefore, the Johnson family will travel 325 miles in 5 hours.
To find out how far the comet will travel in 10 hours, we can use the given information that it travels 8,000 miles in 4 hours.
First, let's calculate the comet's average speed. We can do this by dividing the total distance traveled by the total time taken:
Average speed = Distance / Time
Average speed = 8,000 miles / 4 hours
Average speed = 2,000 miles per hour
Now that we know the comet's average speed, we can calculate the distance it will travel in 10 hours by multiplying the average speed by the given time:
Distance = Average speed * Time
Distance = 2,000 miles per hour * 10 hours
Distance = 20,000 miles
Therefore, the comet will travel 20,000 miles in 10 hours.
