If a car moves for 60 seconds with speed of 90 m/s then its covered distance is……..
a) 54 m
b) 1.5 m
c) 5400 m
d) 540m
Calculation:total time= 60 s
total speed=90 m/s total distance=?
total distance= total speed x total time
total distance= 90 m/s x 60 s= 5400 m
Anathlete moves 20 km in east for 2 hour. Find his speed in km/h?
a) 15 km/h
b) 10 km/h
c) 25 km/h
Calculation:total distance= 10 km
total time taken= 2 h
speed= distance/ time
average speed=20 km/2h
average speed= 10 km/h
Distance-Time Graphs:
A distance-time graph shows how far an object
has travelled in a given time. It is a simple line graph that denotes distance
versus time findings on the graph. Distance is plotted on the Y-axis.
Which
of the following represents relation between two or more quantities in the form
of diagram?
a) table
b)graph
c)
photo
d) line
In distance- time graph, which of the following is taken along y-axis?
a)distance
b) time
c) both a and b
In distance- time graph, which of the following is taken along x-axis?
a) distance
b)time
c) both
d) none of these
