Answer:
Step-by-step explanation:
(a) Since values 5 or up go up and 4.9 and under go down, Naomi could have gone 4555 to 4564.9, as 4555 rounds up to 4560 (and is the largest number that does so) and vice versa for 4564.9
Similarly, Peta could have went from 4550 to 4649.9.
(b)
Peta could have walked 4550 and Naomi 4564.9, so this could be true
Peta could have walked 4649.9 and Naomi 4555, so this could be true
Peta could have walked 4555 and Naomi 4555, so this could be true.
All values here are in the ranges of (a)
(a)
155 to 124.9
1.235 to 1.244
0.01235 to 0.01244
