The answer to this is 50 minutes. by then the runner has gone 11 miles in an hour and 50min and the cyclist has gone 11 miles also
If you have a whole number move the number of exponents in 10 and move left. If you have a decimal, and the 10 is negative exponent, move to the write.
Answer:

Step-by-step explanation:
1. You have the following number given in the problem above:
235,452
2. As you can see, it is smaller than a number with seven digits as 1,000,000.
3. You can rewrite 1,000,000 as an integer power of 10, which must have the following form:

Where
is the exponent that indicates the number of times that 10 is multiplied by itself.
4. Therefore, you have:

Well if you divide 25.6 by 8 and then multiply four by that answer then you have the answer for a, so 4 times 3.2=12.8 , and then you would multiply 25.6 and 12.8 which is 327.68
