The answer is 40.
Steps:
1. Look at the tens place which has the number 4
2. Look at the number behind it
3. Since, the number is 3, you round down to 40
( if your number is less than 5, you round down)
(2x)sqrt 2- 64y2 is the answer
You can infer from this problem that for every 100 m that
John was able to run, it takes him 9.93 seconds. To get how much time is needed
for 26 – mile marathon, you need to divide 26 miles by 100 meters. But first,
you need to convert 26 miles to meters first.
1 mile = 1,609.34 meters
26 miles = 41,842.84 meters
41,824.84 meters / 100 meters = 418.43 x 9.93 seconds =
4,155 seconds or 69.25 minutes
