Question

16. For a race Manish ran at a speed of 6 m/s for 10 seconds. He ran a further 40 m at a speed of 8 mis.
What is his average speed for the race in km/h?​

Answer 1

Answer:

The average speed for the race is 24 km/hr.

Step-by-step explanation:

Distance travelled in first 10 seconds=6m/s × 10s= 60m

Time taken to travel 40m = 40m/8m/s = 5 s

Average speed = Total Distance / Total Time Taken

Average speed = (60m + 40m)/(10s+5s)

Average speed = 100m/15s=100/1000 × 3600/15 km/hr

Average Speed = 24 km/hr

Answer 2

24 km / hr
