Question

Is this answer correct
The question is: a vehicle covers a distance of 72 km in 2hours. Calculate the time period in m/s.
Ans: 720×1000/60×60=7200/60=200/18=72/2=36km/hr=36×5/18=10m/s

Answer 1

Answer:

10 m/s

Step-by-step explanation:

Speed = Distance/Time

= 72/2

= 36 km/hr

We should convert this to m/s

= 1 km/hr = 5/18 m/s

= 36 × 5/18

= 2 × 5

= 10 m/s

Answer 2

Answer:-

→ speed = 10 m/s

Explanation:-

According to the question

Distance = 72 km = 72×1000 metre

Time = 2 hr = 2× 60×60 second

Now Find speed =?

Solution :-

we know that,

$\bf{speed \: = \frac{distance}{time} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{72 \times 1000}{2 \times 60 \times 60} \: \: \: \frac{m}{s} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{720}{72} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 10 \: \: \: \frac{m}{s}$
