Question

how long will an athlete take to run a race of 500 m, if the speed is 50 km per hour ​

Answer 1

Answer:

5 minutes

Step-by-step explanation:

distance = 500m

speed = 50km

distance and speed is given than

500m/50km division by 5

=250/10

=50/5

=25/1

=5/1

=5 minutes is ans

Answer 2

Answer:

18 sec

Step-by-step explanation:

so lets make the speed of 50kmph into mps

50×1000/3600 (1km =1000m) (1hr =3600 sec)

=50×10/36 (two zeros of 1000 and 3600 cancl)

=500/36 (50×10=500)

=250/18 (multiple of two )

=125/9 (multiple of two)

now lets take out the time covered by athlete

(125/9)÷500 (time =s ×d)

= (9/125)×500 (125 cuts 500)

= 9×2

=18 sec
