Ms. Sims traveled to 42 countries in 60 days. At this rate, how many countries

would she travel to in 40 days?

Answer: 28

Step-by-step explanation:

The first step to solve this problem is to figure out how many countries per day ms. Sims travels. Do this by dividing 42 by 60. If the division sign is a "per" symbol she would travel 42 every 60 days.

42/60 is 0.7

So she travels 0.7 countries per day.

Multiplied by 40 days (40 times 0.7) is 28. 28 countries per 40 days
