Question

If 18,000 meter at the speed 4.5 km per hours then time taken is what ?​

Answer 1

Answer:

$4 hr$

Step-by-step explanation:

Speed $s$ = $4.5 km/hr$

Distance $D$ = $18000m = 18km$

$\therefore$ Time taken $t$ = $\dfrac{D}{s} = \dfrac{18}{4.5} = 4 hr$

Answer 2

Answer:

4 hours

Step-by-step explanation:

4.5km/hr = 4500m/hr

time taken = distance/speed

18000/4500

=4

therefore the answer is 4 hours
