Question

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.
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.
