First you can convert 45 miles per hour to feet per hour:
45 × 5,280 = 237,600 feet per hour
Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:
237,600 ÷ 60 = 3,960 feet per minute
Now you just have to divide 3,960 by 60 again to get feet per second:
3,960 ÷ 60 = 66 feet per second
Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:
66 × 3 = 198 feet
Therefore your final answer is <em>198 feet</em> :)
The answer will be 3 or it will be 3/1
In every case the larger number is rounded up to 2E13.
Divide this by 3E8:
2E13 = 200000E8
-------- --------------- is approx equal to 70000 (dollars).

Answer:
Step-by-step explanation:
There are 12 inches in one foot so the equivalent ones are:
1 to 12
This shows that there are 12 inches in one foot so is equivalent.
5 to 60
5/60 = 1/12
This is equivalent because it shows that 12 inches are required to make a foot.
9 to 108
9/108 = 1/12
This is also equivalent for the same reasons as above.
