Question

Help need answered ASAP!

There are two routes Lucas can take to walk to school. Route A is 2 1/8 miles and is 3/8 mile longer than route B. The equation b+3/8=2 1/8 can be used to represent this situation, where b is the length of route B. How many miles will Lucas walk if he takes route B?

A: 1 1/2 miles
B: 1 3/4 miles
C: 2 1/4 miles
D: 2 1/2 miles

Answer 1

1 3/4 because the comments below moi dudes ;)

Answer 2

Option B is correct

`1(3)/(4)` miles will Lucas walk if he takes route B

Explanation:

As per the statement:

There are two routes Lucas can take to walk to school.

Route A is
`2(1)/(8) = (17)/(8)` miles and is 3/8 mile longer than route B

here, b is the length of route B.

The equation we get;

`b+(3)/(8) = 2(1)/(8)`

⇒
`b+(3)/(8) = (17)/(8)`

Subtract
`(3)/(8)` from both sides we have;

⇒
`b = (17)/(8) -(3)/(8) = (17-3)/(8) = (14)/(8) = (7)/(4) = 1(3)/(4)`

Therefore,
`1(3)/(4)` miles will Lucas walk if he takes route B
