A survey 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.
15.8 + 14.2 = 30
The difference in time spent online by teens in these cities is 1.6 hours.
To find the difference in time spent online by teens in Pittsburgh and Miami/Ft. Lauderdale, we need to subtract the number of hours teens in Miami/Ft. Lauderdale spend online from the number of hours teens in Pittsburgh spend online.
Let's define:
P = Number of hours spent online by teens in Pittsburgh (15.8 hours per week)
M = Number of hours spent online by teens in Miami/Ft. Lauderdale (14.2 hours per week)
The equation representing the difference in time spent online by teens in these cities is:
P - M = Difference
Substituting the values:
15.8 - 14.2 = Difference
Calculating the equation:
15.8 - 14.2 = 1.6
Therefore, the difference in time spent online by teens in Pittsburgh and Miami/Ft. Lauderdale is 1.6 hours.
To find the difference in time spent online by teens in Pittsburgh and Miami/Ft. Lauderdale, we can set up and solve an addition equation.
Let's denote the time spent online by teens in Pittsburgh as P, and the time spent online by teens in Miami/Ft. Lauderdale as M.
According to the information provided, P = 15.8 hours per week and M = 14.2 hours per week.
The equation representing the difference in time spent online can be written as:
P - M = Difference
Substituting the given values, we have:
15.8 - 14.2 = Difference
Simplifying the equation, we get:
1.6 = Difference
Therefore, the difference in time spent online by teens in Pittsburgh and Miami/Ft. Lauderdale is 1.6 hours per week.
