Understanding the Problem

To solve this problem, we need to use the formula for calculating time, which is given by:

Time = Distance / Speed

In this case, the distance is 280 miles, and the speed is 50 miles per hour. We need to convert the speed from miles per hour to miles per second, as the answer is required in seconds.

Converting Speed from Miles per Hour to Miles per Second

There are 3600 seconds in an hour. Therefore, to convert miles per hour to miles per second, we divide the speed by 3600.

Speed in miles per second = 50 miles/hour / 3600 seconds/hour

Speed in miles per second = 0.01389 miles/second

Calculating Time

Now that we have the speed in miles per second, we can use the formula for calculating time:

Time = Distance / Speed

Time = 280 miles / 0.01389 miles/second

Time = 20160 seconds

Converting Time to Scientific Notation

To convert the time to scientific notation, we need to express it in the form:

a x 10^b

where a is a number between 1 and 10, and b is an integer.

Time in scientific notation = 2.016 x 10^4 seconds

However, this is not among the answer choices. Let's try to express it in the form:

Understanding the Problem

To solve this problem, we need to use the formula for calculating time, which is given by:

Time = Distance / Speed

In this case, the distance is 280 miles, and the speed is 50 miles per hour. We need to convert the speed from miles per hour to miles per second, as the answer is required in seconds.

Converting Speed from Miles per Hour to Miles per Second

There are 3600 seconds in an hour. Therefore, to convert miles per hour to miles per second, we divide the speed by 3600.

Speed in miles per second = 50 miles/hour / 3600 seconds/hour

Speed in miles per second = 0.01389 miles/second

Calculating Time

Now that we have the speed in miles per second, we can use the formula for calculating time:

Time = Distance / Speed

Time = 280 miles / 0.01389 miles/second

Time = 20160 seconds

Converting Time to Scientific Notation

To convert the time to scientific notation, we need to express it in the form:

a x 10^b

where a is a number between 1 and 10, and b is an integer.

Time in scientific notation = 2.016 x 10^4 seconds

However, this is not among the answer choices. Let's try to express it in the form:

a x 10^b

where a is a number between 1 and 10, and b is an integer.

Time in scientific notation = 0.2016 x 10^4 seconds

This is among the answer choices.
