MA/MN = MB/BP
MA = 46.2 -14
MA=32.2
so
MA/MN = MB/BP
32.2/46.2=x/72.6
46.2x = 72.6 * 32.2
46.2x = 2337.72
x = 2337.72 / 46.2
x = 50.6
1280. 100% of students
X. 60% of student voting for Joan
X=1280•60/100
X=768
Distance covered = 2 km
time taken = 30 minutes = 0.5 hour
speed = distance/time = 2/0.5 = 4 km/h
