Question

A car is moving at uniform speed of $50$ km/hr. It covers $100$ km in how many hours?

• A. $2$
• B. $3$
• C. $4$
• D. $5$

Answer 1

Answer: (A)

$2$

Given that

car is moving at uniform speed of $50$ km/hr.

i.e. A car covers a distance of $50$km in $1$hr.

$\therefore$ distance of $100$km would be covered in $x$ hrs.

By proportionality,

$\frac{50}{1}=\frac{100}{x}$

$\therefore x=\frac{100}{50}$

$\therefore x=2$

Answer is $2$ hrs.
