To answer this item, we let x be the distance that Jimmy drove from his origin and back. Given the speeds, the time it takes for him to travel to and fro are,
t1 = x / 46
t2 = x / 52
respectively.
The equation that would best represent the scenario is,
x/46 - x/52 = 0.6
The value of x from the equation is 239.2.
The trip there takes x/46 which is equal to 239.2/46 which is also equal to 5.2 hours. The travel from the cabin back took 4.6 hours.
A) Both walked 3.5 hours.
B) Hannah walked 3.5 x 3 = 10.5 miles.
For Hannah you multiplied her rate by the time to get total distance.
Penelope walked 7 miles, the black dot on the graph is at the 7 miles on the distance.
C) Hannah walked a faster rate, because she walked further in the same amount of time.
It is translation so Nora is right
For combining like terms: it is 7z
