Question

Brenna has a bike odometer that shows how far she travels. She bikes 8 miles to her friend's house and then both girls bike to the beach. When they arrive, Brenna's odometer shows that she traveled 14 miles in all. Which equation can Brenna use to find the distance d from her friend's house to the beach?

Answer 1

The equation to find the distance d from her friends house to beach is
`d=14-8`.

The distance from her friends house to beach is 6 miles.

Explanation:

Given:

Distance from Brenna's House to friends house = 8 miles

Total Distance from Brenna's House to beach = 14 miles.

We need to write the equation to find the distance d from her friends house to beach.

Solution:

Let the distance from her friends house to beach be denoted by 'd'.

So we can say that;

distance from her friends house to beach is equal to Total Distance from Brenna's House to beach shown in Odometer minus Distance from Brenna's House to her friends house.

framing in equation form we get;

`d=14-8`

Hence The equation to find the distance d from her friends house to beach is
`d=14-8`.

On solving we get;

`d=6\ miles`

Hence The distance from her friends house to beach is 6 miles.

Answer 2

14 = 8 + 2d

Explanation:

Odometer is a device that is equipped in the vehicles to count the distance traveled by the vehicle.

It has been given in the question that,

Distance between beach and her friend's house = d miles.

Distance between Brenna's house and her friend's house = 8 miles

Total distance traveled by Brenna = 14 miles.

Starting from the Brenna's house, we will add each distance traveled till the end of her journey and will make it equal to the 14 miles.

So,

Total distance = Distance between Brenna's house and her friend's house + Distance between her friend's house and beach + Distance between beach and her friend's house

Thus, we can now put the values as,

14 = 8 + d + d

We will get the final equation as

14 = 8 + 2d
