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
- 5 1/4 <span>÷ 2 3/4 =
= - 21/4 </span><span>÷ 11/4
= - 21/4 * 4/11
= - 21/11
= - 1 10/11
