Answer:
9360 meters
Step-by-step explanation:
3.6 * 60 = 216 meters/minute
216 * 30 = 6480 meters in a half hour
1.6 * 60 = 96 meters/minute
96 * 30 = 2880 meters in a half hour
6480 + 2880 = 9360
Distance = speed × time
Sasha runs at a constant speed of 3.6 m/s for half hour. This means that the distance she covers while running would be
3.6 × 0.5 = 1.8 miles
Then she walks at a rate of 1.6 m/s for half an hour. This means that the distance she covers while walking would be
1.6 × 0.5 = 0.8 miles
Total distance that Sasha covered in running and walking for 60 minutes is
1.8 + 0.8 = 2.6 miles
The sum would be
4x^2-x+1
add like terms.
3x^2+x^2
4x^2
4x+-5x
