Question

Behrgan takes 2.4 minutes to complete a loop, while McKenna takes 1.6 minutes. What is the ratio of Behrgan's time to McKenna's time for completing one loop?

A) 4:3
B) 3:2
C) 2:3
D) 3:4

Answer 1

The ratio of Behrgan's time to McKenna's time is obtained by expressing their individual times in minutes as fractions and simplifying. The correct ratio is 3:2, where Behrgan takes 1.5 times longer than McKenna to complete a loop.

Step-by-step explanation:

The question asks to find the ratio of Behrgan's time to McKenna's time for completing one loop. To find this ratio, we compare the times it takes for each of them to complete a loop. Behrgan takes 2.4 minutes and McKenna takes 1.6 minutes.

To find the ratio, we express both times as fractions with a common denominator or as decimals. As decimals, Behrgan's 2.4 minutes and McKenna's 1.6 minutes are equivalent to 24/10 and 16/10 respectively. After simplifying these fractions by dividing both numerator and denominator by 8, we get 3/2 and 2/2 respectively.

Now we can see that Behrgan's time is 3/2 or 1.5 times McKenna's time. Hence, the ratio of Behrgan's time to McKenna's time is 3:2, which corresponds to option B.
