Respuesta :
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
45 × 6 = 270 minutes
270 ÷ 60 = 4.5 hours
4.5 hours = 4 hours 30 minutes = 4 1/2 hours
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
⇒[tex]\text{Unit rate per day} = \frac{3}{4} = 0.75 hours[/tex]
We have to find the how many hours does she exercise during the 6 days.
[tex]\text{Number of hours } = \text{Unit rate per day} \times 6[/tex]
Substitute the given values we have;
[tex]\text{Number of hours } = 0.75 \times 6 = 4.5[/tex]
Therefore, 4.5 hours does she exercise during the 6 days
