Answer 1

I hope you can calculate the rest. That scares me a bit.

Answer 2

Answer:

Average Speed = 40 meters/minutes

Average 40 meters/minutes the runner cover.

Step-by-step explanation:

Given:

9 laps of a 400 meters track every day.

His timings (in minutes) for four consecutive days.

Find:

An average how many meters/minutes does the runner cover

solution :

Distance =

⇒ 9 laps of a 400 meters track 4 day

so that,

⇒ 9 × 400 × 4 (day)

⇒ 3600 × 4

⇒ 14400

Distance = 14400 meter

⇒ Time = 88,96,89 and 87 (in minutes)

Average Speed = Total Distance / Total Time

⇒ Average Speed = 14400 / 88 + 96 + 89 + 87

⇒ Average Speed = 14400 / 360

⇒ Average Speed = 40

Therefore,

Average Speed = 40 meters/minutes.
