L = (1⅕)W= (6/5)W
LW = 480 in²
(6/5)W² = 480
W² = 480 × ⅚ = 400
W = 20 in
L = (6/5)W =24 in

Answer:
- A) 290 km
- B) 4 hours
- C) 72.5 km/h
Step-by-step explanation:
Let distance be d and time t
<u>At 75 km/h speed the distance is</u>
- d = 75(t - 48 min) = 75(t - 48/60 hours)
<u>At 50 km/h speed the distance</u> is
<u>Since the distance is same, we get the equation:</u>
- 75(t - 48/60) = 50t + 40
- 75t - 75*4/5 = 50t + 40
- 75t - 60 = 50t + 40
- 75t - 50t = 40 + 60
- 25t = 100
- t = 4 hours
<u>A) The distance between A and B</u>
<u>B) Time is </u>
<u>C) The speed = d/t</u>
- Speed = 290/4 = 72.5 km/h
