b) 7 days
c) 4 days
d) 6 days

Answer 1

Uri works approximately 3 days to earn $205.51. The actual distance between the two cities on the map is approximately 595 miles.

Step-by-step explanation:

To find the number of days Uri works to earn $205.51, we can set up a proportion using the given information: $342.51 is earned in 5 days, so the proportion is 342.51/5 = 205.51/x. Cross-multiplying gives us 342.51x = 1027.55. Dividing both sides by 342.51, we find that x ≈ 3 days.

To find the actual distance between two cities on a map with a scale of 2 inches = 140 miles, we can set up a proportion. The proportion is 2 inches/140 miles = 8.5 inches/x miles. Cross-multiplying gives us 2x = 1190. Dividing both sides by 2, we find that x ≈ 595 miles.
