we have

using a graph tool
see the attached figure
For t=0 d=4 -------> the y-intercept
that means that at the time t=0 the house was four units away.
For t=60 min d=0 -------> x-intercept
that means he was already at home at the time t=60 minutes.
therefore
the graph of this equation represents the walk towards the house
The same reason 4 dimes and 4 pennies aren't equal.
To put it into decimal terms, 4/10 is 0.40 (or forty cents), whereas 4/100 is 0.04 (or four cents)
This is a problem of guess and check; there's no easier way to do it.But in this case you must have an odd number of nickels to make the 5 cents, so your answer is 9 nickels.you can check this by multiplying each one by .05:
9*.05=.45
the rest of the coins left, are 8 of them, and their dimes.
.10*8=.80
.80+.45= 1.25
