Question

The distance covered by a car moving with a speed of 36 km/h in 15m is (a) 0.9 km (b) 9.0 km (C) 90 km (d) 900 km

Answer 1

The correct answer is option - (b)

Explanation :

GIVEN :

Speed of car per hour = 36km

Time Taken = 15m

Change into hours :

1 hour = 60 minutes

= 15/60 hours

= 1/4 hours

We know that,

Distance = Speed × Time

= 36 × 1/4

= 9km

Therefore, the distance covered by a car is 9km.

Answer 2

$\huge\sf\underline{Answer}$

Distance covered by the car is (b) 9.0 km

Given :

Speed of a car = 36 km/h

Time taken = 15 minutes

Converting the time into hour:-

= 15/60 hours

= 1/4 hours

As we know that,

Distance = Speed × Time

= (36 × 1/4) kilometres

= 9 kilometres

Hence the distance covered is 9 kilometres.

More information:-

Distance :- The change of position of a moving body is called the distance travelled by the body. The S.I unit of distance is metre (m).

Speed :- The rate of change of position of a body with respect to time is know as speed of the body. The S.I unit of Speed is metre per second (m/s).
