The gardener wanted to find the best water to use for growing his plants. If plants need a more neutral pH water for optimal gro
wth, then a pH that is too high or too low will result in less plant growth. The gardener had 4 groups of water treated plants: 1. pH 4 acid water;
2. tap water of pH 6.8;
3. near neutral deionized water;
4. pH 8 basic water.
He would water everyday and every 3 days the gardener would measure and record the height of the plants in centimeters. After 5 weeks the gardener concluded that the tap and deionized water were almost double the height as the pH 4 and pH 8 water.

The Earth's circumference is 24,901 miles. Assuming an apple is 3 inches wide: 3.7 trillion apples is 3/12/5280*3000000000000=142045454.545 miles. That is 142045454.545/24901=5704.408 times around the Earth.
