Answer 2

Answer:

It takes 8 hours to cover 800 km

Step-by-step explanation:

Let the time taken to cover 800 km be x hrs.

Given,

• $T_1$ = 17 hrs
• $D_1$ = 1700 km
• $T_2$ = x hrs
• $D_2$ = 800 km

The Relation is :

$\bold{T_1D_2 = T_2D_1}$

∴ $T_2$ can be determined by,

$\bold{T_2 = \frac{T_1D_2}{D_1}}$

∴ $T_2 = \frac{17\times800}{1700}$

⇒ $T_2 = \frac{30600}{1700}$

⇒ $T_2$ = 8 hours

∴ It takes 8 hours to cover 800 km.
