# I am sorry but I am not good at math, this may seem like a dumb question but I don't do well with word problems? I can't figure it out, maybe I am making it too hard on myself, can someone point me to the right direction?

. The distance from Philadelphia to Sea Isle City is 100 mi. A car was driven this distance using tires with a radius of 14 in. How many revolutions of each tire occurred on the trip?

## First find the circumference of the tire.

C = pi * diameter Your answer will be in inches.

Then convert 5,280 feet (1 mile) to inches.

Divide the inches in a mile by the circumference of the tire.

Multiply by 100.

## No worries! Understanding word problems can be challenging sometimes. Let's break it down step by step.

First, we need to find the circumference of each tire. The formula to find the circumference of a circle is C = 2Ï€r, where C represents the circumference and r represents the radius.

In this case, the radius of each tire is given as 14 inches. So, the circumference of each tire would be:

C = 2Ï€(14 inches)

To make calculations easier, let's simplify this to:

C â‰ˆ 88 inches (rounded to the nearest whole number)

Now that we know the circumference of each tire, we can determine the number of revolutions made by the car. The distance the car traveled is given as 100 miles.

To find the number of revolutions, we need to convert the given distance from miles to inches and then divide it by the circumference of each tire:

Number of revolutions = (Distance traveled in inches) / (Circumference of each tire)

To convert miles to inches, we know that 1 mile is equal to 63,360 inches (1 mile = 5280 feet, and 1 foot = 12 inches).

So, the distance traveled in inches would be:

Distance traveled in inches = 100 miles * 63,360 inches/mile

Now, we can calculate the number of revolutions using the formula:

Number of revolutions = (100 miles * 63,360 inches/mile) / (88 inches)

Calculating this expression will give us the final answer, which represents the number of revolutions made by each tire during the trip.

Please note that the final answer will be in decimal form since dividing by the circumference might not result in a whole number.
