pls show work

Answer 1

40 seconds

Step-by-step explanation:

A unicorn is running at rate of 3 meters/second. To find how long it'll take to get at the end of a 120 meter rainbow, we'll have to find the "time".

The distance is given to be 120 meters and speed is given as 3 meters/second.

Our formula for speed is:

`\displaystyle{v = (s)/(t)}`

where v is speed, s is distance and t is time:

`\displaystyle{3 = (120)/(t)}`

Solve for t, multiply both sides by t:

`\displaystyle{3 \cdot t= (120)/(t)\cdot t}\\\\\displaystyle{3t= 120}`

Divide both sides by 3:

`\displaystyle{(3t)/(3) = (120)/(3)}\\\\\displaystyle{t= 40 \ \, \sf{seconds}}`

Therefore, it will take 40 seconds for a unicorn to reach at the end of rainbow.
