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 spee
g100num [7]

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
