Question

If you ride a pterodactyl for 3 hours at 10 mph and then ride a stegosaurus for 1 hour at 2 mph, what would be your average speed?​

Answer 1

Answer:

8 mph

Step-by-step explanation:

The equation for average speed is:

$average\ speed=\frac{total\ distance}{total\ time}$

Let's start by finding the distance for each animal:

$d=st\\d=3h*10\frac{m}{h}\\d=30m$

$d=st\\d=1h*2\frac{m}{h}\\d=2m$

Now, we can find the average speed:

$average \ speed=\frac{30mi+2mi}{3hr+1hr}=\frac{32mi}{4hr}=8\frac{mi}{h}$

8 mph
