Answer:
15. 24.5 m
16. 11 cm
17. 29.75 m
18. 1.4 cm
Explanation:
15. each 1 cm in the drawing is equal to 3.5 m in real life so a distance of 7 cm in the drawing would be 7×3.5 because in the drawing, you are traveling 7 times the distance of 1 cm so in real like you would travel 7 times the distance of 3.5 m
16. the distance in real life is 38.5 m so to find the distance in the drawing, you would need to divide the real life distance by 3.5 so 38.5÷3.5=11 cm
17. to calculate real life measurement, you would need to add up all the distances David's aunt traveled in the drawing
1 cm + 4.5 cm + 2 cm + 1 cm = 8.5 cm
next, to calculate real distance, you would multiply 8.5 and 3.5 so 8.5×3.5=29.75 m
18. To find distance on cindys map, we will need to first find real life distance on original map and then convert the real life distance into cm on the scale that cindy has on their map.
On the original map where 1 cm = 3.5 m, davids house to the library is 2 cm so to find real life distance from this map would multiply 3.5 by 2 so 3.5×2=7 m
Next, we need to convert this to the scale on Cindy's map, where 1 cm = 5 m so now we need to divide 7 by 5 to get to cm so 7÷5 = 1.4 cm on cindys map
