Question

A car covers a distance x, while moving at 54
km/hr in 15 sec. The value of x is
(a) 2.25 km
(b)
5.40 km
(c) 0.225 km
(d) 13.5 km​

Answer 1

Answer:

(c) 0.225 km

Step-by-step explanation:

54 km/ hr = 54*5/18 m/s = 15m/s

Distance traveled in 15 sec = 15*15 = 225m

= 0.225 km

Answer 2

Answer : Option (C) 0.225 km

Solution :

Given that :

Speed = 54 km/h = 54×5/18 = 15 m/sec

Time = 15 sec.

As we know that :

Speed = Distance/Time

=> Distance = Speed × Time

=> Distance = 15 × 15

=> Distance = 225 m.

As we also know that :

1 km = 1000 m

=> 1 m = 1/1000 km

=> 225 m = 225/1000 = 0.225 km

So, car covers distance of 0.225 km
