Question

Please help! Average speed. Show work!

Answer 1

3.78 m/s

Option D is the right option.

solution,

Distance travelled=340 metre

Time taken= 1.5 minutes ( 1 minute=60 seconds)

=1.5* 60

=90 seconds

Now,

Average speed:

`\ (distance \: travelled \: )/(time \: taken) \\ = (340 \: m)/(90 \: s) \\ = 3.78 \: metre \: per \: second`

Hope this helps...

Good luck on your assignment..

Answer 2

3.78 m/s

Step-by-step explanation:

Recall that the formula for average speed is given by

Speed = Distance ÷ Time taken

Where,

Speed = we are asked to find this

Distance = given as 340m

Time taken = 1.5 min = 1.5 x 60 = 90 seconds

Substituting the values into the equation:

Speed = Distance ÷ Time taken

= 340 meters ÷ 90 seconds

= 3.777777 m/s

= 3.78 m/s (round to nearest hundredth)
