Question

A joker moves 5 steps forward and 3 steps backward. If each step is of one

meter and he takes one second to cover one step what would be the distance

travelled and the displacement covered by the joker after 20s.


Please tell the full working​

Answer 1

Explanation:

Total distance = 5 + 3 = 8 steps

Since 1 step equals 1 meter

Therefore 8 steps equals 8 meter

Total displacement = 5 - 3 = 2 steps

Since 1 step is of 1 meter

Therefore 2 steps equals 2 meters

After 20 seconds

Total distance = 5+3+5+3+4 = 20 meters

Total displacement = 5 - 3 + 5 - 3 + 4 = 8 meters
