Light travels at 186,000 miles per second. How many FEET does it travel in a microsecond? (A microsecond is a millionth of a sec

Maslowich

1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual

zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle $A=a\cdot b$ assuming $a=600km, \ b=450km$ and get $A=600\cdot 450=270000km^2$ which is an actual area of Colorado
