Question

An athlete runs 10 km in 50 minutes. Calculate the speed of the athlete in m/sec.

Answer 1

As Per Given Information

Athelete runs 10Km in 50 mins .

It means distance covered by athelete is 10km & time taken to cover 10km distance is 50min.

Before going to solve this problem

First we convert the unit

=> Distance = 10×1000 m

=> Distance = 10000 m

Now,

=> Time taken = 50×60

=> Time taken = 3000s

Finding the speed of athelete in m/s

Using Formulae

`\bf \:Speed \: = (Total \: Distance \: Covered)/(Time \: Taken)`

Putting the value we obtain

`\sf \twoheadrightarrow \: Speed \: = (10000)/(3000) \\ \\ \sf \twoheadrightarrow \: Speed \: = \cancel (10000)/(3000) \\ \\ \sf \twoheadrightarrow \: Speed \: = 3.33m {s}^( - 1)`

• So, the speed of the athelete is 3.33m/s.
