First, look into my attachment
∠A = ∠C
2m = 70°
m = 70°/2
m = 35°

The sum of angles inside parallelogram is 360°
∠A = ∠C
∠B = ∠D

∠A + ∠B + ∠C + ∠D = 360°
70° + n + 70° + n = 360°
140° + 2n = 360°
2n = 220°
n = 110°

m=70/2=35

n=(360-70*2)/2=110

The local train heading for Westford at 60km/h and the express train heading for Eastford at 80 km/h pass each other at Centervi

Wewaii [24]

Answer:

The maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.

Step-by-step explanation:

Local train stats:

Rate = 60 km/h

Distance = x km

Time = x/60 hours

Express train stats:

Rate = 80 km/h

Distance = $(195-x)$ km

Time = $(195-x)/80$ hours

Now we will equate both the times.

$x/60 =(195-x)/80$

$x/3= (195-x)/4$

$4x= 585-3x$

$7x= 585$

x = 83.57 km

$195-x=195-83.57= 111.43$ km

Hence, the maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.
