Question

Your family visited Disney World Orlando, FL. The 823.5 mile trip took 11.5 hours. How fast did your family travel?

Answer 1

As we need to calculate speed, we use the equation "s = d ÷ t"
To write the known facts, "s = 823.5 ÷ 11.5"
Using a calculator =

`(823.5)/(11.5)`
= 71.61m/s (to the nearest 2 d.p)

Answer 2

To solve this, use the equation speed = distance / time. S = D/t for short. The equation automatically gives you the distance and time it took, so this is pretty simple.

823.5/11.5 = 71.608695652173913043478260869565 miles per hour.

71.61 mph would probably work though. XD
