45w is 12:00 noon what will be the local mean time at 90?​
zheka24 [161]

Answer:

9 pm

Explanation:

If the local mean time at 45° W is 12:00 noon, what will be the local mean time at 90°E?

The lines of longitude run from north to south, measuring distance from east to west of the prime meridian. The line of longitude are used to measure time.

Each 1° = 4 minutes

Change in degrees (we add since it is west and east) = 45° + 90° = 135°

Change in time = 135 * 4 minute = 540 minutes

change in time = 540 minutes = 9 hours

local mean time at 90°E = 12 noon + 9 hours = 9 pm

gavmur [86]

"Green revolution" is a term used for rapid increases in crops especially 'wheat' and 'rice' yields in developing countries which was introduced to Mexico and India by Norman Borlaug and Ms Swaminathan in the early 20th Century. They used improved crop varieties combined with the expanded use of fertilizers and other chemicals to boost crop production in developing countries. The goal of the Green Revolution was to increase the yields of wheat and rice by improving agronomic technology. This helped developing countries to overcome food defects.
