Question

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

Answer 1

Answer: $61.9miles/hr$

Step-by-step explanation:

given data:

distance travelled by the car =  195 miles

time taken = 3 hours and 15mins

solution

average speed of the car

$= \frac{195miles}{3hrs15mins} \\\\= 61.9miles/hr$

Answer 2

Answer:

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

Step-by-step explanation:

The equation of the average speed os given by:

$v=\frac{\Delta x}{\Delta t}$ (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)

$v=\frac{195}{3.25}$

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

I hope it helps you!
