Question

A sprinter travels a distance of 300 m in a time of 27.34 seconds. What is the sprinter's average speed rounded to 4 sf?

Answer 1

Step-by-step explanation:

Given A sprinter travels a distance of 300 m in a time of 27.34 seconds. What is the sprinter's average speed rounded to 4 sf?

• Distance travelled by sprinter = 300 m
• Time taken 27.34 s
• Speed = distance / time taken
•          = 300 / 27.34
•          = 10.972 m/s
• Now 1 km / h = 1000 / 3600 m/s
• So 1 m/s we get 3600 / 1000 = 18/5 km/h
• Therefore 10.97 m/s will be 10.972 x 18/5
•            = 39.5025 km / hr

Therefore average speed will be 39.5025 km / hr

Answer 2

Given:-

A sprinter Travels distance of 300 m

In a time of 27.34 seconds.

To find:-

What is the sprinter's average speed rounded to 4 sf.

Solution:-

- Distance travelled by sprinter = 300m

Time taken = 27.34s

- By using the formula of speed, which is

Speed = distance / time

Speed = 300/27.34

Speed = 10.972m/s

- As we known that the SI unit of average speed is km/h but answer is in m/s. So,

Now, 1 km/h = 1000/3600 m/s

- So, 1 m/s =3600/1000 = 3.6

Therefore, 10.972 m/s will be

= (10,972) * (3.6)

= *39.4992 km/h*
