Question

How far did the car travel during the 10 sec trip? Position (km) Time (sec) 5 0 8 2 10 4 16 6 20 8 20 10 Answer choices- 10 km 15 km 20 km (this is the one I chose) 79 km

Answer 1

15 km

Explanation:

Given the table:

`\begin{center}\begin{tabular}{ c c}Position(Km) & Time(sec) \\ 5 & 0 \\ 8 & 2 \\ 10 & 4 \\ 16 & 6 \\ 20 & 8 \\ 20 & 10 \\\end{tabular}\end{center}\\`

To find:

The distance traveled by the car.

Solution:

Here, we are given the position of the car after an interval of 2 seconds.

We are not given the distance traveled.

If the distance traveled would have been given, then distance traveled by car = Sum of all the values = 5 + 8 + 10 + 16 + 20 + 20 = 79 km

Then the answer would have been 79 km.

As, we are given the position here, so the distance traveled will be equal to final position minus the initial position.

Distance traveled in 10 seconds = Position at 10 seconds - Position at 0 seconds = 20 - 5 = 15 km
