Question

what time is taken by Rajan to cover a distance of 360 km by a motorcycle at a speed of 10 metre per second

Answer 1

Answer:

Step-by-step explanation:

→ 1 m/s = 3.6 km/hr

→ 10 m/s = 3.6 × 10 = 36 km/hr

→ time is taken by Rajan to cover a distance of 360 km

→ time= distance/speed

→ time= 360/36 = 10 hr

so rajan will take 10 hours to cover a distance of 360 km by a motorcycle at a speed of 10 metre per second.

Answer 2

Given,

The speed of Rajan's motorcycle is 10 meters per second.

To Find,

If Rajan wants to cover 360km with the motorcycle how much time is required.

Solution,

We know that,

• 60×60 seconds = 3600 seconds = 1hour.
• And 1km = 1000 meters.

So 360 km = 360×1000 meters =360000meters.

The motorcycle of Rajan took 1 second to cross 10 meters.

So with that, he can go 1 meter in $\frac{1}{10}$ seconds.

∴Rajan can go 360000 meters in 360000× $\frac{1}{10}$ seconds = 36000 seconds.

Now 36000 seconds = 36000×$\frac{1}{3600}$ hours =10 hours.

Hence, To cover a distance of 360km with the motorcycle with a speed  10metre per second, the time is taken by Rajan us 10 hours.
