प्रश्न

Given below is the distance-travelled by an elephant across a forest with uniform speed. Complete the data of the table given below with the idea of uniform speed.

Distance (m) 0 4   12   20
Time (s) 0 2 4   8 10
योग

उत्तर

Distance (m) 0 4 8 12 16 20
Time (s) 0 2 4 6 8 10

Distance/Time = `4/2 xx 4 = 16/22` = 8

Distance/Time = `4/2 xx 8 = 32/2` = 16

Time/Distance = `10/20 xx 12 = 12/2` = 6
