The answer is actually 850 miles. If you multiply 400 by 2, you get 800. 1/2 is eqivalent to 50. (In this problem) So, 800+50=850.
800 miles double 1 inch
1000
2.5 x 400 = 1,000 miles
One-and-a-half times 400
when 1 inch = 400 miles then 2.5 inches = 2.5 x 400 = 1,000 miles
800 miles double 1 inch
400 x 2.5 = 1000 miles
1000
2.5 x 400 = 1,000 miles
1,000 miles. 400+400=800+200=1,000
One-and-a-half times 400
when 1 inch = 400 miles then 2.5 inches = 2.5 x 400 = 1,000 miles
If a map scale indicates that 1 inch equals 400 miles, then 2 12 inches (which is equivalent to 2.5 inches) would equal 2.5 times 400 miles. Therefore, 2.5 inches on the map represents 1,000 miles in reality (2.5 x 400 = 1,000).
If 400 miles is represented by 1 inch, then 2.5 inches represents 2.5 x 400 = 1000 miles.
Assuming you mean "two and a half inches"? The answer is 1000 miles
1in. = 4 2in. = 8 half of 4 = 2 8+2=10 so two and a half is equal to 1000 miles
820 inches
