Question

In a 1000 m race, Alok reaches the finishing line 40 seconds before Abi and beats him by 200m. What is Alok’s speed?

Answer 1

alok speed =
$speed = \frac{distance}{time}$
1000 - 800 = 200 m --- distance
$speed = \frac{800}{40}$
speed = 20 m / sec

Answer 2

Answer:6.25 m/s

Step-by-step explanation:

as given alok beat abi by 200m and 40 seconds. it means abi cover 200m in 40 seconds.

speed of abi = distance /time

= 200 / 40

=5 m/s

time taken by abi in whole race = distance traveled / speed

= 1000 /5

=200 seconds

as alok take 40 seconds less than abi.

alok completed his racn 160 seconds

so speed of alok = distance / time

= 1000 / 160

=6.25 m/s
