Answer:
4.5 hours
Step-by-step explanation:
we know that
A postal carrier can deliver to 130 houses in 2.5 hour
so
using proportion
Find out how many hours will it take to deliver to 234 houses
[tex]\frac{130}{2.5}\ \frac{houses}{hours} =\frac{234}{x}\ \frac{houses}{hours} \\\\x=234(2.5)/130\\\\x=4.5\ hours[/tex]
