Answer:
Total distance covered on each week = 5 × 3 = 15 miles
Step-by-step explanation:
She runs north for 0.75 miles and west for 1 miles . Then she runs a straight line home. The illustration will form a right angled triangle. The straight line she runs home will be the hypotenuse of the triangle.
Using Pythagoras's formula one can calculate the hypotenuse.
c² = a²+ b²
c² = 0.75² + 1²
c² = 0.5625 + 1
c² = 1.5625
c = √1.5625
c = 1.25 miles
Total distance covered each weekday = 1.25 + 0.75 + 1 = 3 miles
Total distance covered on each week = 5 × 3 = 15 miles
Note that weekdays are Monday to Friday
Based on the information given, the total distance covered will be 15 miles.
Based on the information given, we've to calculate the hypothenuse and this will be:
- c² = a²+ b²
c² = 0.75² + 1²
c² = 0.5625 + 1
c² = 1.5625
c = √1.5625
c = 1.25 miles
Therefore, the total distance covered will be:
= 1.25 + 0.75 + 1 = 3 miles.
Therefore, the total distance covered weekly will be:
= 3 × 5
= 15 miles.
