Hi everybody! I'm stuck with this maths question. May you help me? Please show your working clearly using distance line method.

Qn 1. A dog starts chasing a cat when hy are 12m apart. Fo every 7m that the dog runs, the cat runs 4m. How far does the dog have to run to catch up with the cat?

Hey Shirley,

Following pls find my worked solution:

Q9

Based on the faster speed of the Dog (7m/unit time),

Number of Unit Time (Catch Up) = 12 ÷ ( 7 - 4 ) = 12 ÷ 3 = 4

Distance for Dog to catch up with the cat = 7 × 4 = 28 m

=======

Trust this helps

Do let me know again if this is different from your <Answerkey> or if there's further clarification.

Cheers,
Edward
