Question

If adrian needed to be at his grandmother's house in 3 hours and it was 150 miles away, at what speed would he need to drive to get there?.

Answer 1

50mph

Explanation:

Speed (v) is equal to distance (d) divided by time (t)

so we have the formula
`v=(d)/(t)`

Adrian needs to be at his grandmother's house in 3 hours so
`t=3`

His grandmother's house is 150 miles away so
`d=150`

now we can plug these values into our formula and we get
`v=(150)/(3)`

`(150)/(3) =50`

So, Adrian needs to drive at 50 miles per hour to get to his grandmother's house in three hours.
