Answer 2

1. i) 10 km/h

iii) B to C

iv) C to D

v) distance = area

(first find the area of the trapezium and area of the rectangle. then add them to get the value.)

Area of trapezium = 0.5×(a+b)×h

= 0.5×(10+35)×3

= 67.5

Area of rectangle = L×L

= 5×35

=175

Total area in first 8 hours = 67.5 + 175

= 242.5 m
