Nitin cycles to school daily as shown in the distance time graph. study the graph carefully and answer the questions that follows

Dear student,

a) The answer is 1000 m = 1 km
b) Part A, B and D shows Nitin is moving since the distance increases sith time.
c) In part C, he stops for the signal light for 40 sec.
d) 400 m
e) In part A,
distance = 400 m and time = 80 s
speed = distance/time = 400 / 80 = 5 m/s
f) In part B,
distance =800 - 400 = 400 m and time = 100 - 80 = 20 s
speed = distance/time = 400 / 20 = 20 m/s
g) Average distance = total distance / total time = 1000/200=5 m/s

Regards
