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

Answer:
a) 44
b) 11
c) 4
Step-by-step explanation:
a) x + 46 = 90
x = 90 - 46
x = 44
b) 9x + 81 = 180
9x = 180 - 81
9x = 99
x = 11
c) (5x + 30) + 40 = 90
(5x + 30) = 90 - 40 = 50
5x + 30 = 50
5x = 50 - 30
5x = 20
x = 4
