Step-by-step explanation:
Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.
a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as
The exponent of 10 is a negative number because you moved the decimal point to the right.
b) Similarly, you have to move the point 9 times to the right so the answer is
Time taken before they are 2640 feet is 146.67 seconds
<em><u>Solution:</u></em>
The distance is given by formula:
<em><u>Ton travels at 8 feet per second</u></em>
Let us assume, time taken = t
speed = 8 feet per second
Then, distance is given as:
Distance covered by Ton = 8t
<em><u>Bob travels at 10 feet per second</u></em>
Then, distance is given as:
Distance covered by Bob = 10t
How long will it take before they are 2640 feet
Which means,
Distance covered by Ton + Distance covered by Bob = 2640
Thus time taken before they are 2640 feet is 146.67 seconds
<h3><u>Method 2:</u></h3>Since trains are moving in opposite directions, their speeds must be added
speed = 8 + 10 = 18 feet per second
Given distance = 2640 feet
Therefore, time taken is:
Thus time taken before they are 2640 feet is 146.67 seconds
