Question

Heather and Mathew walk with an average velocity of 0.81 m/s Eastward. If it takes 16.2 minutes to walk to the store, what is their displacement? Your answer should be in meters, but don't include units in your answer.

Answer 1

Step-by-step explanation:

Average velocity of Heather and Mathew given is 0.81 m/s. They are walking with a constant speed and in this case, Total displacement can be calculated by multiplying velocity × total time taken.

Total time taken is 16.2 mins. As velocity has secs in its units, first convert mins into secs.

`16.2 \: \rm{mins} = 16.2 * 60 \: \rm{secs}`

`= 972 \: s`

Calculating their total displacement,

= 0.81 m/s × 972 s

= 787.32 m

But as you asked not to include m in the final answer, the answer of this problem is 787.32.
