Answer:
Step-by-step explanation:
Given question is incomplete; here is the complete question,
Katie runs from her house, east 5 blocks, south 3 blocks, west 5 blocks, and north 4 blocks before walking back home. Regarding her jog only: Her total time it takes her 35 minutes. If city block is about 0.5 miles (0.8 km), what is her velocity in mi/h and m/s?
Katie runs from her house, East 5 blocks, South 3 blocks, West 5 blocks and North 4 blocks.
Since, velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]
Displacement of Katie from initial position = (3 + 3) blocks
= 6 blocks
Since, each block measure 0.5 miles,
Displacement = 6 × 0.5
= 3 miles
Time taken to cover the distance = 35 minutes ≈ 0.583 hours
Therefore, velocity of Katie = [tex]\frac{3}{0.583}[/tex]
= 5.15 miles per hour towards South
Displacement (in m) = 6 × 0.8
= 4.8 km
≈ 4800 m
Velocity (in m per hour) = [tex]\frac{4800}{0.583}[/tex]
= 8233.27 m per hour towards South
