Question

A car drives 195 miles in 3 hours and 15 minuits. What is the average speed of the car?

Answer 1

Answer:
`61.9miles/hr`

Explanation:

given data:

distance travelled by the car = 195 miles

time taken = 3 hours and 15mins

solution

average speed of the car

`= (195miles)/(3hrs15mins) \\\\= 61.9miles/hr`

Answer 2

The average speed is
`v=60 miles/h`

Explanation:

The equation of the average speed os given by:

`v=(\Delta x)/(\Delta t)` (1)

here:

Δx is just 195 miles

Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)

So we just need to put this into the equation (1)

`v=(195)/(3.25)`

Therefore, the average speed is
`v=60 miles/h`

I hope it helps you!
