Question

Find the velocity of a truck that travels 75 miles north in 2.5 hours.

Answer 1

30 miles per hour/north

Answer 2

`\boxed {\boxed {\sf A.\ 30 \ mph \ north}}`

Explanation:

Velocity can be found by dividing the displacement by the time.

`v=(s)/(t)`

The displacement of the truck is 75 miles north. The time is 2.5 hours.

`s= 75 \ miles \ north \\t= 2.5 \ hr`

Substitute the values into the formula.

`v=(75 \ miles \ north )/( 2.5 \ hr)`

Divide.

`v= 30 \ miles \ north / hr`

`v= 30 \ miles/hour \ north`

The velocity of the truck is 30 miles per hour north.
