192 = 3w^2 solve using square root

W=8

Step-by-step explanation:

First you divide both sides by 3 then you square root both sides getting 8

192/3=3w^2/3

64=w^2

w=8

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
