Ben is 4 times as old as Ishaan and is also 6 years older than Ishaan.
How old is Ben?

Answers

Given :-

  • Ben is 4 times as old as Ishaan.

  • Ben is 6 years older than Ishaan.

To find :-

  • age of Ben

Let :-

  • Ishaan age be x
  • Ben age be 4x

Solution :-

✪According to question:-

Ben is 6 years older than Ishaan

So :-

  • Ben age - Ishaan age = 6 years

put supposed values

  • 4x - x = 6
  • 3x = 6
  • x = 6 ÷ 3
  • x = 6/3
  • x = (2 × 3)/3
  • x = 2/1
  • x = 2

Original Ages :-

  • Ishaan age = x
  • Ishaan age = 2 years

  • Ben age = 4x
  • Ben age = 4(2)
  • Ben age 4 × 2
  • Ben age = 8 years

✪Verification :

1st condition:-

  • Ben age - Ishaan age = 6 years

put original ages

  • 8 - 2 = 6
  • 6 = 6

LHS=RHS

Hence verified !

Required answer :-

Ben's age =8years

Paula's time swimming in the Ironman Triathlon was 1 hour 25 minutes. Her time biking was 5 hours longer than her swimming time. She ran for 4 hours 50 minutes. How long did it take her to complete all three parts of the race? Use the model to help you organize your thinking.

Answers

Answer: 12 hrs 40 mins

Step-by-step explanation:

The swimming time was 1 hour 25 minutes.

Her biking time was 5 hours longer than the swimming time so it was:

= 1 hr 25 mins + 5 hours

= 6 hours 25 mins

Her running time was 4 hrs 50 mins.

Add them all up to find the amount of time ran. First add up the minutes:

= 25 + 25 +50

= 1 hr 40 minutes

Hours = 1 + 6 + 4

= 11 hours

Total:

= 11 + 1 hr 40

= 12 hrs 40 mins
