i-okay,whats yoour problem? maybe i can help :D
First, we need to find out how many houses that Hannah received money from. We can do this by dividing the total amount of money she received by the amount she received per house.
780 / 5 = 156
Hannah received money from 156 houses.
To find the amount of houses she did NOT collect money from, we just need to subtract the amount of houses that she DID receive money from away from the total amount of houses in her neighborhood.
278 - 156 = 122
Hannah did not collect money from 122 houses.
Hope this helped! =)
We are given
Ronaldo delivers the papers at the rate of 6 papers in 24 minutes
so, number of papers =6 in time =24 minutes
so, firstly we can find rate
rate = ( number of papers)/( time taken)

now, we can find times
Time for 56 papers:
we are given
number of papers =56
rate is

now, we can find time



Time for 41 papers:
we are given
number of papers =41
rate is

now, we can find time



now, we can find time difference

so, we can plug values
