Asurvey of teens showed that teens in pittsburgh aged 12-17 spend 15.8 hours per week online. teens in miami/ft. lauderdale spend 14.2 hours per week online. write and solve an addition equation to find the difference in time spent online by teens in these cities.

1.6 hours per week is the difference in time spent online by teens in these (Pittsburgh and Miami/Ft. Lauderdale) cities.

Step-by-step explanation:

Given:

Teens in Pittsburgh aged 12-17 spend 15.8 hours per week online. Let take as,

                 P = 15.8 hours per week

Teens in Miami/Ft. Lauderdale spend 14.2 hours per week online. Let take this as,

               M = 14.2 hours per week

We need to find the difference in time spent online by teens in both cities. It means 'difference (d)'. Hence,

              Difference (d) = P - M

              Difference (d) = 15.8 - 14.2

              Difference (d) = 1.6 hours per week

1.6 hours per week is the difference in time spent online by teens in these cities (Pittsburgh and Miami/Ft. Lauderdale).
