Question:
A student bikes to school by traveling first 1.00 miles north, then 0.500 miles west and finally 0.200 miles south.
If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover
Given Information:
distance towards north = dn = 1.00 mi
distance towards west = dw = 0.500 mi
distance towards south = ds = 0.200 mi
Required Information:
distance covered by bird = db = ?
Answer:
distance covered by bird = 0.94 miles
Explanation:
As you can see in the attached image, by applying the Pythagoras theorem,
db = √(dn - ds)² + dw²
db = √ (1.0 - 0.20)² + 0.50²
db = √ 0.80² + 0.50²
db = 0.94 miles
Therefore, the bird would cover a distance of 0.94 miles
The answer is or maybe 7283
