Answer 2

Answer:

Time taken = 20.625 hr / 20 hr 37 min 30 s

Step-by-step explanation:

Let the distance covered in 72 km be x.

Given,

• Distance covered ($D_1$) = 1485 km
• Time ($T_1$) = 1 hr
• Distance covered ($D_2$) = x km
• Time ($T_2$) = 72 hr

In 1 hr ⇒ 1485 km

In 72 hr ⇒ x km

There is a relation,

$T_1D_1 = T_2D_2$

∴ $D_2$ = $\frac{T_1D_1}{D_2}$

⇒ $D_2$ = $\frac{1485}{72}$

∴ D₂ = 20.625 hr = 20 hr 37 min 30 s
