Answer: 3:08
Step-by-step explanation:
They started riding at 2:47 and reached the soccer field 21 minutes later.
The time they go to the field is therefore:
= 2:47 + 21 minutes
= 3:08
<em>Adding time:</em>
<em>First find out the number of minutes needed to take 2:47 to 3:00:</em>
<em>= 60 minutes in an hour - 47</em>
<em>= 13 minutes </em>
<em>Then remove the 13 minutes from the 21 minutes of riding:</em>
<em>= 21 - 13</em>
<em>= 8 minutes </em>
<em>Add this 8 to 3:00:</em>
<em>= 3 + 8</em>
<em>= 3:08</em>
H(t) = -16t^2 + 32t + 7
The 7 shows the height the ball was hit from
Setting H(t) = 0 and solving for t yields t= 2.2 seconds when it hits the ground
