Question

it takes Serina 0.25 hour to drive to school. Her route is 16 km long. What is Serinaa's average speed on her drive to school?

Answer 1

64km/hr
if it takes .25 hrs to travel 16km you would be traveling 16km every .25hrs, but you need it in km/hr so you multiply .25 by 4 and 16 by 4. you get 64km/hr

Answer 2

`64(Km)/(h)`

Step-by-step explanation:

we have the following data

`time (t)= 0.25h\\distance (d)= 16Km`

They ask us to calculate the speed, and this is the relationship between the distance traveled and the time taken to complete it.

As we want to calculate the average speed of Sarina we can use the following formula

`V=(d)/(t)`

replace the data in the formula

`V=(16Km)/(0.25h)\\ V=64(Km)/(h)`

The average speed of sarin is
`64(Km)/(h)`
