Question

Gina walks 3 mph for 4 hrs. How far did she walk? 1.3 mi 7 mi 0.75 mi 12 mi

Answer 1

Answer:
`12 mi`

Step-by-step explanation:

Velocity
`V` is mathematically defined as:

`V=(d)/(t)` (1)

Where:

`V=3 (mi)/(h)` is Gina's velocity

`t=4 h` is the time Gina spends walking

`d` is the distance Gina has walked

Isolating
`d` from (1):

`d=Vt` (2)

`d=(3 (mi)/(h))(4 h)` (3)

Finally:

`d=12 mi` This is the distance Gina has walked
