Marguerite sailed 4 hours on Saturday and 3 hours on Sunday. Each day, she sailed at a rate of 11 miles per hour. Which statements are true? Check all that apply.

Question

She sailed for 4 hours.
She sailed for 7 hours.
She sailed 44 miles in all.
She sailed 77 miles in all.

Answer 1

Let's calculate the total hours and total distance Marguerite sailed.

1. Total hours of sailing:

   • Saturday: 4 hours
   • Sunday: 3 hours
   • Total hours = 4 hours + 3 hours = 7 hours

2. Distance sailed each day:

   • Distance = speed × time
   • On Saturday: 11 miles/hour × 4 hours = 44 miles
   • On Sunday: 11 miles/hour × 3 hours = 33 miles

3. Total distance sailed:

   • Total distance = Distance on Saturday + Distance on Sunday
   • Total distance = 44 miles + 33 miles = 77 miles

Now we can evaluate the statements:

1. She sailed for 4 hours. (False, she sailed for a total of 7 hours)
2. She sailed for 7 hours. (True)
3. She sailed 44 miles in all. (False, she sailed a total of 77 miles)
4. She sailed 77 miles in all. (True)

So the true statements are:

• She sailed for 7 hours.
• She sailed 77 miles in all.
