Question

X covers 1km in 8 min 40 sec while y covers the same distance in 10 min. By what distance does x defeat y

Answer 1

${\huge {\mathfrak {\orange {Answer :-}}}}$

X covers 1 km in 520 secs.

Y covers 1 km in 600 secs.

Thus, Y's speed = 1000/600 = 5/3 m/s.

Thus, in 520 secs Y covers distance

= 5/3 * 520 = 2600/3

Now, (1000 - 2600/3)

= 400/3 = 133.3

Therefore, X defeats Y by 133.3 metres.

Answer 2

Step-by-step explanation:

X covers 1 km in 520 secs.

Y covers 1 km in 600 secs.

Thus, Y's speed = 1000/600 = 5/3 m/s.

Thus, in 520 secs Y covers distance

= 5/3 * 520 = 2600/3

Now, (1000 - 2600/3)

= 400/3 = 133.3

Therefore, X defeats Y by 133.3 metres...
