#### To determine

**To estimate:**

The distance traveled by car

#### Answer

*155* ft.

#### Explanation

**1) Concept:**

Area under the graph is

*A=limn→∞∑i=1nfxi∆x*

where,

*∆x=b-an & xi=a+i∆x*

2) **Calculation:**

Here, to find the distance traveled by the car means the area under the curve.

So that is given in the graph.

Interval is *0, 6* with six intervals.

So find out * ∆x*.

*∆x=b-an=6-06=1*

So the distance traveled by car is

*A=∑i=i6fxi∆x*

*=551+401+281+181+101+41*

*=155 ft*

**Conclusion:**

The distance traveled by the car is *155* ft.
