Given:

1 mile = 1.61 km

1 km = 1000 m

Answer 1

Step-by-step explanation:

1 mile = 1.61 km and 1 km = 1000 m

The speed of light is
`3* 10^8\ m/s`. We need to convert it into miles per hour.

1 m = (1/1000) km

`3* 10^8\ m=(3* 10^8)/(1000)\\\\=3* 10^5\ km`

1 km = (1/1.61) miles

`3* 10^5\ km =(3* 10^5)/(1.61)\\\\=1.86* 10^5\ \text{miles}`

So,
`v=1.86* 10^5\ \text{miles/s}`

Hence, this is the required solution.
