PLEASE HELP I NEED IT RN Sanjit drives the 45 km distance between York and Leeds.
He then drives a further 42 km from Leeds to Blackpool.
Sanjit's average speed between York and Leeds was 54 km/h.
It also took Sanjit 35 minutes to travel from Leeds to Blackpool.
Work out Sanjit's average speed (in km/h) for his total journey
from York to Blackpool​

it is impossible.

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
