Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
16t + 14t = 270
30t = 270
t = 270/30
t = 9 seconds
B:
He ran 9 sec at 16 ft/sec, therefore:
9 * 16 = 144 ft
Answer:
2(t) or 2 * t
Step-by-step explanation:
Both of those are multiplying 2 and t, which is also what 2t means.
45/100 = 9/20
Work: divide by 5
It is b 4/3+2/3 is 6/3 and 6/3 divided by 1/3 is 2/3x
