Pihu starts her car at 9 a.m. to reach her office, which is 20 km away. She covers the first 10 km in 30 minutes and reaches her office at 10 a.m. Pihu's motion is _______.
uniform motion
To determine the nature of Pihu's motion, let's examine the details provided:
- First 10 km is covered in 30 minutes.
- The total distance to the office is 20 km, and she reaches by 10 a.m.
Now, calculate her speed for the first 10 km:
The speed for first 10 km = distance/time = 10 km / 0.5 hours = 20 km/h.
Pihu covers the remaining 10 km in the next 30 minutes, from 9:30 a.m. to 10 a.m., therefore:
The speed for remaining 10 km = distance/time = 10 km / 0.5 hours = 20 km/h.
Since Pihu maintains a constant speed of 20 km/h throughout her journey, her motion is best described as uniform motion, because uniform motion occurs when an object travels equal distances in equal intervals of time.
