Question

Berry Boulevard is 4 4/5 Miles long.There are two traffic lights on Berry Boulevard every 2/5 mile after the street begins .There are 2 stop signs every 1 3/5 miles .How many traffic lights are there on Berry Boulevard

Answer 1

Answer: There are 24 traffic lights on Berry Boulevard.

Explanation:

Since we have given that

Total length of road =
`4(4)/(5)=(24)/(5)\ miles`

Number of roads on every
`(2)/(5)\ mile` = 2

So, According to unitary method,

In every
`(2)/(5)\ mile`, number of roads = 2

In every 1 mile, number of roads =
`(5)/(2)* 2=5`

So, in every
`(24)/(5)\ miles,` the number of roads =
`(24)/(5)* 5=24`

Hence, there are 24 traffic lights on Berry Boulevard.
