Grace's walking rate is 1.5 meters per second. her house is 90 meters from the fountain. how many seconds will it take her to reach the fountain?

Speed=1.5

Distance=90 meters

Time=?

Distance= time × speed

Thus,

T=distance/speed

   =90/1.5

   = 60 second

   = 1 minute  

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
