Step-by-step explanation:

Answer:
L =80
w=60
Step-by-step explanation:
P =280
L =w +20
=>L +w=280 :2 =140
w+20+w=140
2w=140 - 20
2w =120
w=120 :2 =60
L=60 +20 =80
P =2L +2w
P =2 ×80 +2 ×60
P=160 +120
P=280
V = d / t => t = d / V
V ≥ r ; d = 350 => t = d / V ≤ 350 / r
Then, t ≤ 350 / r, which is option C.
