Question

Example 4: Aryan makes a camel journey of 20 km. The camel travels at
12 km/hr for the first part of the journey but then conditions worsen and the
camel can only travel at 4 km/hr for the second part of the journey. The journey
takes 3 hours. Find the length of each part of the journey. Solve the problem by
both algebraic method and graphical method.

Answer 1

Answer:

12,8

Step-by-step explanation:

As we know there is 20 km long journey

and total time taken is = 3 hour

let us consider that he cover X km distance by 12 km per hour

then X/12+ (20-x)/4 = 3

by LCM

X+60-3x= 36

-2x= -24

X = 12

it means he cover 12 km distance with speed of 12kmph while rest (8) by 4 km ph
