Answer:
-38/3
Step-by-step explanation:
At first, you times 12 and 3, which is 36
Then you do 36+2, which is 38
Don't forget the negative sign!!!!
So it is -38/3
Hope it helped!~❤️
Speed of light in vacuum = 2.998 x 10^8 m/s
1m = 1/1000 km and 1s = 1/3600 hr
Speed of light in vacuum = (2.998 x 10^8 x (1/1000)
km) / (1/3600) hr
Speed of light in vacuum = 10.792 x 10^8 km/hr
Now
1km = 0.6213 mi
1hr = 60min
As Speed of light in vacuum = 10.792 x 10^8 km/hr
Speed of light in vacuum = 10.792 x 10^8 x (0.6213mi)
/ 60min
Speed of light in vacuum = 0.1117 x 10^8 mi/min
<span>Speed of light in vacuum = 11.17 x 10^6 mi/min</span>

let's firstly convert the mixed fractions to improper fractions and then subtract, bearing in mind that the LCD of 4 and 2 is 4.
