Answer:
2
Step-by-step explanation:
Kelly ran at an average speed of 8 miles per hour. If she finished the race in one and a half hours that means she ran 12 miles.
8=x
?=3/2x
12=x
We now know the road is 12 miles long. Ava has an average speed of 6 miles so she will finish it in 12/6 hours.
12/6=2

Answer:
Step-by-step explanation:
s + r = 181
r = 119 + s
s + 119 + s = 181
2s + 119 = 181
2s = 181 - 119
2s = 62
s = 62/2
s = 31 <=== there are 31 senators
r = 119 + s
r = 119 + 31
r = 150 <=== there are 150 representatives
