Can someone please help me ASAP

i) 30 minutes

ii) 50 km/h

Step-by-step explanation:

Part 1:

1540 - 1600 is pnt 1 to pnt 2; 1 km per hour. (20 minutes)

15km at  90km/h = 10 min

20 + 10 = 30 minutes

Part 2:

10 km/h + 90 km/h = 100km/h

Average = /by number of factors;

100 km/h  / 2 = 50 km/h (Average journey speed)

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
