Question

If a person travels $150km$ in $5$ hours, then the time taken by him to travel $180km$ is

• A. $3$
• B. $4$
• C. $8$
• D. $6$

Answer 1

Answer: (D)

$6$

$150:5=180:x$

product of means = product of extremes

$5\times 180=150\times x$

$x=\frac{5\times 180}{150}$

$x=\frac{900}{150}$

$x=6$
