Question

An athlete runs at 30 km/h. In how much time will he run a race of 200 metres ? *

(a) 20 seconds
(b) 24 seconds
(c) 32 seconds
(d) 36 seconds​

Answer 1

Step-by-step explanation:

speed = 30km/h

distance = 200mtr = 0.2 km

now, speed = distance / time

Time = distance/ speed

= 0.2/30 = 1/150 hour = 24 sec

therefore b option is correct

Answer 2

Answer:

(b) 24 seconds

Step-by-step explanation:

30km into m = 30,000m

1hr = 3600 seconds

so,

to go 30000m athlete take 3600sec

so for 1 m he will take 3600/30000

& for 200 m he will take 3600/30000*200

i.e 24 seconds
