speed is constant I.e. 10kmph
we have to find distance between t=20 and t=30minutes
first we have to convert 10kmph into metre per minute
so distance travelled in 10 minutes
=166×10=1660metres or 1.66 kilometres
we have to find distance between t=20 and t=30minutes
first we have to convert 10kmph into metre per minute
so distance travelled in 10 minutes
=166×10=1660metres or 1.66 kilometres
SOODAANYA:
166.66×10=1666.6
t=0 and t=30 then answer
i have taken speed approximately that's why there is a minor difference in my answer
if we take t=0 and t=30 then we multiply 166.66×30 which is equal to 4999.8metres or 5km {approx.}
ok
thanks
it's ok

Given:
From the graph, we can observe that, the speed is constant which is 10Km/h
First, let us convert 10 Km/h into meter per minute
1 Km = 1000 m, one hr = 60 minute
10 Km/h = 10 x 1000/60 = 166.67 meter per minute
We have to find the distance traveled between 20 to 30 minutes.
Since speed is constant, if we find the time difference, we find the distance covered just by multiplying speed and time.
Time difference = 30 min – 20 min = 10 minutes
Distance covered = 10 x 166.67 = 1666.7 m/min which is approximately 1.67 Km.
