Question

Convert 3.00 x 10^5 km/sec to miles/hr. (1 mile = 1.609 km)

Answer 1

`3* 10^5\ (km)/(s)=6.71* 10^8\ \text{miles per hour}`

Step-by-step explanation:

In this problem, we need to convert
`3* 10^5\ km/s` to miles per hour

We know that,

1 mile = 1.609 km

1 hour = 3600 seconds

`3* 10^5\ (km)/(s)=3* 10^5\frac{((1)/(1.609)\ \text{miles})}{(1)/(3600)\ \text{hour}}\\\\=6.71* 10^8\ \text{miles per hour}`

Hence,
`3* 10^5\ (km)/(s)=6.71* 10^8\ \text{miles per hour}`
