Answer 1

Step-by-step explanation:

Given Time taken by 5 members winner team of a 5x1000 meters relay race are 2.55,2.15,2.30,2.60 and 2.40 minutes respectively. Find the team's average speed in km/hour

• Now time taken by 5 members will be 2.55, 2.15, 2.30, 2.60 and 2.40 minutes.
• Adding this we get 12 minutes..
• We know that average speed = distance / time taken.
•                                                = 5000 m / 12 min
•            1000 m = 1 km
•          So 5000 m = 5 km
•      60 min = 1hr
•  So 12 min = 12 / 60  
•                  = 1 / 5 hrs
•          So speed = 5 / 1/5
•                           = 5/0.2

                          = 25 km / hr

Therefore the team's average speed in km/hour is 25 km /  hr
