The Singh family takes a road trip every year. This year, the family recorded the total distance traveled after each hour and plotted the points on the graph below.

Question

The graph titled Singh family trip shows distance travelled in kilometers on y-axis and Hours spent driving on x-axis. There are points at (0, 0), (1, 75), (2, 150), (3, 225), (4, 300), and (5, 375).

What is the speed at which the Singh family traveled?

A.
50 kilometers per hour

B.
75 kilometers per hour

C.
100 kilometers per hour

D.
150 kilometers per hour

Answer 1

To determine the speed at which the Singh family traveled, we can calculate the speed using the formula for speed, which is:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

From the data provided, we see that in 5 hours, the family traveled a total distance of 375 kilometers.

Using the formula:

\[ \text{Speed} = \frac{375 \text{ km}}{5 \text{ hours}} = 75 \text{ km/h} \]

Thus, the speed at which the Singh family traveled is 75 kilometers per hour.

The correct answer is B. 75 kilometers per hour.
