On a map 0.75 inch represents 80 miles. Two cities that are 1025 miles apart will be how far apart on a map round to nearest ten

icang [17]

The cities are 9.6 inches apart on map.

Step-by-step explanation:

Given,

80 miles in actual = 0.75 inch

1 mile = $\frac{0.75}{80}\ inch$

Distance between two cities = 1025 miles

1025 miles on map = $1025*\frac{0.75}{80}\\$

$1025\ miles\ on\ map=\frac{768.75}{80}\\\\1025\ miles\ on\ map=9.6\ inches$

The cities are 9.6 inches apart on map.
