Question

please give mi answer.​

Answer 1

Given,

• (Uniform) Speed of car = (x + 8) km/hr
• Time taken in journey = (x + 8) hrs

We know,

$\boxed{ \bullet \:\textbf{ \pink{Distance}} \tt{ = \green{Speed } \times \green{Time}} \: }$

Therefore,

$\text{Distance between Chennai } \& \: \text{Ooty } \\ \tt \implies Speed \times Total \: taken \: time \\ \sf \implies( x+ 8) \times (x + 8) \\ \sf \implies x(x + 8) + 8(x + 8) \\ \sf \implies {x}^{2} + 8x + 8x + 64 \\ \sf \implies {x}^{2} + 16x + 64$

Thus,

• Distance between Chennai & Ooty is (x² + 16x + 64) Kms.

Answer 2

We know that ,

Speed = distance / time

Here,

Speed = x + 8 km/hr

Time = x + 8 hrs

So,

diastance = speed * time

d = (x+8)(x+8)

d = (x+8)²

d = x² + 2*8*x + 64

d = x² + 16x + 64
