Answer 1

Step-by-step explanation:

We know from the question that the fathers age is 50.

We also know that we have to take 5 years from that 50 so that is 50–5=45.

We also know that we then have to divide the answer by 3 so 45/3 =15.

The son is 15 years old.

Answer 2

Question 1:

Adman's father is 50 years old. He is 5 years older than three times Adman's

age. What is Adman's age?

⠀⠀⠀⠀⠀⠀⠀

Solution:

⠀⠀⠀⠀⠀⠀⠀

☯ Age of Adman's father is 50 years.

☯ Let Present age of Adman be x years.

⠀⠀⠀⠀⠀⠀⠀

$\underline{\bigstar\:\boldsymbol{According\:to\: Question\::}}$

⠀⠀⠀⠀⠀⠀⠀

Father is 5 years older than 3 times Adman's age.

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 50 = 3x + 5$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 50 - 5 = 3x$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 50 - 5 = 3x$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 45 = 3x$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf x = \cancel{ \dfrac{45}{3}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\purple{x = 15\;years}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ Hence, Adman's age is 15 years.

Question 2:

A car covers a distance of 212.4 km in 4 hours.

a) Find the distance covered by the car in an hour?

b) Find the distance covered by the car in 3.5 hours?

⠀⠀⠀⠀⠀⠀⠀

Solution:

⠀⠀⠀⠀⠀⠀⠀

Distance cover by car in 4 hours = 212.4 km

⠀⠀⠀⠀⠀⠀⠀

Distance cover by car in 1 hour = $\sf \dfrac{212.4}{4} = \bf{53.1\;km}$

⠀⠀⠀⠀⠀⠀⠀

Distance cover by car in 3.5 hour = 53.1 × 3.5 = 185.85 km
