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.
I think so:
Your working out is probably just the same as my working out!
1000 + 1200m = 1500 + 1175m
1200m - 1175m = 1500 - 1000
25m = 500
m = 500/25
m = 20 <== they are the same at 20 months...they will both be 25,000
1) the longest side is 5cm and the perimeter is 12cm
2) longest side is 12.04 or just 12
3) 241 miles apart
4) Yes it is
