Question

Find out distance covered when speed is 15m/sec and time is 10 hours

Answer 1

Given that,

Speed = 15 m/s

Time = 10 hrs = 36,000 secs

We know that,

Speed = Distance / Time

Therefore, Distance = speed × time

Distance (s) = 15 × 36,000

Distance (s) = 5,40,000 mtrs

Distance (s) = 540 kms.

Answer 2

Answer:

Given:

Speed (s) = 15 m/s and time(t)= 10 hours.

First convert the unit of speed m/s into km/hr

Since, 1 m = $\frac{1}{1000} km$ ;  1 sec = $\frac{1}{3600} hr$

1m/sec = $\frac{\frac{1}{1000}}{\frac{1}{3600}}  km/hr$ = $\frac{3600}{1000} =3.6 km /hr$

then,

15 m/s = $15 \times 3.6$ km/hr = 54 km/hr

Then the speed (s) = 54 km/hr

Use the formula : Distance = $Speed \times time$

Distance = 54 km/hr $\times$10 hr = 540 km

Therefore, the distance covered is, 540 km.
