Question

Brielle exercises for 3/4 hour each day for 6 days in a row. Altogether how many hours does she exercise during the 6 days?

Answer 1

3/4 hour = 45 minutes
45 × 6 = 270 minutes
270 ÷ 60 = 4.5 hours
4.5 hours = 4 hours 30 minutes = 4 1/2 hours

Answer 2

Answer:

4.5 hours does she exercise during the 6 days

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per second or 4 kilometer per hour.

As per the statement:

Brielle exercises for 3/4 hour each day

⇒$\text{Unit rate per day} = \frac{3}{4} = 0.75 hours$

We have to find the how many hours does she exercise during the 6 days.

$\text{Number of hours } = \text{Unit rate per day} \times 6$

Substitute the given values we have;

$\text{Number of hours } = 0.75 \times 6 = 4.5$

Therefore, 4.5 hours does she exercise during the 6 days
