1. Solution :

Given ,

• Distance = 7150 km
• Speed = 780 km/h

We need to find ,

• Time taken = ?

As we know that ,

Speed = Distance/Time

Simplifying ,

Time = Distance/Speed

Substituting ,

• Distance = 7150 km
• Speed = 780 km/h

⇒ Time = 7150/780

Time = 9.166 h

Hence , time taken by the body to travell 7150km with a speed of 780 km/h = 9.166 hrs

• v = u + at
• W = FS
• P = F/A
• F = m × a
• S = ut + 1/2 at²
• v² – u² = 2as
• v² = – 2gH
