Question

You arrive to science class 45 seconds after needing your social studies class which is 90 m away. How fast did you travel? m/sec

Answer 1

Speed = distance divided by time
90m divided by 45s
=2m/sec

Answer 2

The rule of the speed is

`s=(d)/(t)`

d is the distance

t is the time

Since you took 45 seconds to go to the science class, then

t = 45 sec

Since the distance from the social studies class is 90 meters, then

d = 90 m

Substitute them in the rule above to find your speed

`\begin{gathered} s=(90)/(45) \\ s=2\text{ m/sec} \end{gathered}`

Your speed is 2 m per sec
