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
उत्तर
Elevation relative to the sea level at the end of the ride
= [380 + 540 – 268 + 116 – 152 + 490 – 844 + 94] m
= [380 + 540 + 116 + 490 + 94 – 268 – 152 – 844] m
= [1620 – 1264] m
= 356 m
