Answer:
2x²y+(x²y-2xy²) = 3x²y-2xy²
(5xy²-x²y) +3x²y = 5xy²-2x²y
4x²y+(x²y+xy²) = 5x²y+xy²
x²y+(-2xy²-4x²y) = -3x²y-2xy²

Answer:
the least required speed is 103.88 km/h
Step-by-step explanation:
Data provided in the question:
Total distance = 270 km
Total time to reach = Time between 8 a.m and 11:15 a.m i.e 3.25 hours
Now,
For the distance of 110 km speed was 100 km/h
therefore, the time taken to cover 110 km =
=
= 1.1 hour
For another 43 km speed was 42 km/h
therefore, the time taken to cover 43 km =
=
= 1.0238 hours
Now,
The distance left to be covered = 270 - 110 - 43 = 117 km
Time left = 3.25 h - 1.1 h - 1.0238 h = 1.1262 h
Thus required speed =
= 103.88 km/h
Hence, the least required speed is 103.88 km/h
