d equals 4 and 5 eighths inches where 1 half inch equals 355 miles
d/4 5/8 = 355/(1/2)
Cross multiply and solve for d.
To convert inches to miles, we need to use the given conversion factor of 1/2 inch = 355 miles.
First, let's find out how many half inches are in 4 and 5/8 inches. To do this, we divide 4 by 1/2, which equals 8. Then we add the remaining 5/8 to get the total number of half inches. That gives us 8 + 5/8 = 45/8 half inches.
Now we can use the conversion factor to calculate the equivalent distance in miles. We multiply the number of half inches (45/8) by the conversion rate (355 miles):
(45/8) * 355 = 1987.5 miles
Therefore, d is equal to 1987.5 miles when e is 4 and 5/8 inches.
