Question

Over a half-mile stretch of road, there are 7 evenly spaced street signs. Find the distance

Answer 1

Answer:

We know that:

Over a half-mile stretch of road, there are 7 evenly spaced street signs.

If we assume that there is a sign right at the beginning and another right at the end, then the distance between each sign will be equal to the total distance divided by the total number of signs minus one because the distance is measured in pairs of consecutive signs, if we have 7 signs, then we will have 6 pairs of consecutive ones ( 1st and 2nd, 2nd and 3rd, 3rd and 4th, ...)

(0.5mi)/6 = 0.83... mi

So, rounding to the second decimal after the decimal point, the distance between each sign is 0.83 miles.
