Question

An athlete running at 36km/hr took 25 seconds to cover a certain distance. Find the distance covered in metres?​

Answer 1

Answer:

Given: speed(v) = 36km/h and time(t) = 25 sec

Find: distance covered?

Step-by-step explanation:

distance(d) = v × t      (1)

Convert the speed in m/sec

so,

      v = (36×1000m)/(1×3600s)

      v = 10 m/sec

     put the value of v in equation (1)

      d = v × t

      d = 10 × 40 = 400 m

Hence, the distance covered is 400 meters.

Answer 2

Given that speed(v) = 36k/h and time(t) = 40 sec

We have to find distance (d)

First convert speed into m/s

v = (36*1000m)/(1*3600s)

v = 10m/s

d = v*t = 10*40

d = 400 m

Ans: 400 meter
