Question

Find out the distance covered when speed =15m/sec,time=10 hour

Answer 1

there are 3600 seconds in 1 hour
so,in 10 hour there are 3600×10=36000

so,Distance=speed ×time
distance=15m×36000=540000m

convert 540000m into km I.e.,=540000/1000=540km

Answer 2

QUESTION.......

As Given;

Find out the distance covered when speed =15m/sec,time=10 hour

SOLUTION......

As we know that ;

Distance = speed × time .

So here,

The speed is :-15 meters/ second
Time is :- 10 hours .

=>Before multiplying " speed and time " we have to ensure that they are in like quantity .

But here ;
=>Speed is in "seconds"
=> Time is in "hours".

We have to convert speed into hour :-

CONVERSION ........

1 Hour= 3600 seconds .

So,

15m / second
= 54000 meters per hour .

Per 10 hours = 54000× 10 = 5,40,000 meters .

So Distance covered is :-

5,40,000 METERS .

OR

540 KILOMETERS .
