Question

Hannah drove 450 miles to her brother's house at an average speed of 60 miles per hour. How long did she take?

Answer 1

It took Hannah approximately 7.5 hours (or 450 minutes) to get to her brothers house.

This is because 450 divided by 60 is 7.5.

Answer 2

Hannah drove 450 miles to her brother's house at an average speed of 60 miles per hour. How long did she take? (Time)

`t=(Distance)/(Speed)`

`t=(450)/(60)`

`t=7.5hours`

Remember, time must be converted to seconds as it is the unit for time.

7.5 hours to seconds

1 hour = 3600 seconds

3600 seconds * 7.5 hours

`=\fbox{27000 seconds}`
