Question

Who ran at faster pace?
Misha ran $9$ laps in $15$ minutes and Myra ran $12$ laps in $25$ minutes.

• A. Misha ran faster than Myra
• B. Myra ran faster than Misha
• C. Both ran at equal pace
• D. Cannot be determined

Answer 1

The correct option is A Misha ran faster than Myra

Misha: $\frac{9}{15}\times \frac{5}{5}=\frac{45}{75}$
Myra: $\frac{12}{25}\times \frac{3}{3}=\frac{36}{75}$
$\therefore$ Misha ran faster as $\frac{45}{74}>\frac{36}{75}$.
