formulate problem and solution
Given: Time taken by light to travel 1 meter is roughly 3×10 raise to negative 8 seconds
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
3*10^-8 seconds = 1 m
3 seconds = ?m
I'll let you find the solution.
4x10^8
Problem: Calculate the time taken by light to travel a given distance.
Solution:
To solve this problem, we need to use the given information that the time taken by light to travel 1 meter is approximately 3×10^-8 seconds.
1. Determine the distance for which you want to calculate the time taken by light to travel. Let's say the distance is 'd' meters.
2. Use the given speed of light to set up a proportion. Since the speed of light is constant, we can set up the following proportion:
(Time taken by light to travel 'd' meters) / ('d' meters) = (Time taken by light to travel 1 meter) / (1 meter)
Mathematically, this can be represented as:
T / d = (3×10^-8 s) / (1 m)
Where T represents the time taken by light to travel 'd' meters.
3. Cross-multiply and solve for T:
T = (3×10^-8 s) × d
4. Substitute the given value of 'd' into the equation to calculate the time taken by light to travel the distance.
This solution provides a general method to calculate the time taken by light to travel a given distance using the given information.
