Tan 40° = 6 / AC
AC = 6 / tan 40°
AC = 6 / .8391
AC = 7.15

AB² = 6² + 7.15²
AB² = 36 + 51.123
AB² = 87.12
AB = 9.33

Answer:

To travel half a distance Abby requires 1.5 hrs.

Step-by-step explanation:

Given:

Abby is going to ride her bike to her friend's house that lives 6 miles away.

Distance = 6 miles

She can ride her bike at a rate of 2 miles per hour.

Speed = 2 miles per hour

We need to find the time required to ride her bike half of the distance.

Now Distance = $\frac{6}{2} =3 \ miles$

Now Time required can be calculated by Dividing distance with speed.

Time (hours) = $\frac{3}{2}=1.5 \ hrs$

Hence To travel half a distance Abby requires 1.5 hrs.
