Gwar [14]

Answer: There are 24 traffic lights on Berry Boulevard.

Step-by-step explanation:

Since we have given that

Total length of road = $4\dfrac{4}{5}=\dfrac{24}{5}\ miles$

Number of roads on every $\dfrac{2}{5}\ mile$ = 2

So, According to unitary method,

In every $\dfrac{2}{5}\ mile$ , number of roads = 2

In every 1 mile, number of roads = $\dfrac{5}{2}\times 2=5$

So, in every $\dfrac{24}{5}\ miles,$ the number of roads = $\dfrac{24}{5}\times 5=24$

Hence, there are 24 traffic lights on Berry Boulevard.
