Question

The coordinates on a map for City A are (57, 11) and those for City B are (121, 79). Note that coordinates represent miles. Find the distance between the cities to the nearest mile.

Answer 1

93 miles

Explanation:

Use the distance formula:

d =
`√((x2 - x1)^2 + (y2 - y1)^2)`

Plug in the values:

d =
`√((121 - 57)^2 + (79 - 11)^2)`

d =
`√(4096 + 4624)`

d =
`√(8720)`

d = 93.4

= 93 miles

Answer 2

93 miles.

Explanation:

To find this answer, we can use the distance formula: D= SQ root of (X2 - X1)^2 + (Y2-Y1)^2

Then, we have to plug in the corrdinates accordingly:

D = SQ root of (121 - 57)^2 + (79 - 11)^2

D = SQ root of (64^2) + (68^2)

D = SQ root of 4096 + 4624

D = SQ root of 8720

D = 93.3809402394

D rounded to the nearest mle is 93 miles

Hope this helps :)
