You are at an elevation 380 m above sea level as you start a motor ride. During the ride, your elevation changes by the following metres: 540 m, - 268 m, 116 m, -152 m, 490 m, -844 m, 94 m. What is your elevation relative to the sea level at the end of the ride
Solution:
To answer the given question let us examine the problem using the properties of integers.
To calculate elevation relative to the sea level at the end of the ride we will use integer rules and simplify the equation.
= [380 + 540 - 268 + 116 -152 + 490 - 844 + 94]
= [380 + 540 + 116 + 490 + 94 - 268 - 152 - 844]
= [1620 - 1264]
= 356 m
✦ Try This: Evaluate 380 - 540 + 268 - 116 +152 - 490 + 844 - 94.
To evaluate the given expression 380 - 540 + 268 - 116 +152 - 490 + 844 - 94 we can simply apply integer rules and get the required final value.
