Your question is calling the figure ABCD, but the image is showing PQRS


Using the letters that you wrote:

Because the figure was only rotated and not scaled , the sides with the same letters would still be the same

So AB would be the same as A'B' ( Length of AB = Length of A′B)

and

BC = B'C'

CD = C'D'

AD = A'D'


Or by the picture:

PQ = P'Q'

QR = Q'R'

RS = R'S'

PS = P'S'

A train leaves at 11:32 and arrives at 13:24. It travelled at an average speed of 85 km/h.
Blababa [14]

Answer:

<h2>33.2Km</h2>

Step-by-step explanation:

<h3>Time used for journey = </h3>

13 : 24 - 11 : 32 = 1 : 92

1 : 92 = 1 hour 92 minutes

1 hour 92 minutes = 2 hours 32 minutes

<h3>changing 32 minutes to hours</h3>

1 h = 60 min

x = 32 min

x= 32 /60

x= 8/15 hours

<h3>Adding the 2hours to 8/15 hours</h3>

8/15 h + 2 h = 38 / 15

<h3>Using formula for distance</h3>

Distance = Speed × Time

Distance = 85km / h × 38 /15 h

Distance = 33.15 km

To 1DP = 33.2
