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

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
