## Introduction to Data Interpretation

#### Data Interpretation

Direction: A motorist and a scooterist made a journey of 120 km at the same time and from the same place. The graph shows the progress of the journey made by each person. Study the graph and answer the questions.

1. What was the speed of the scooterist during the journey? (in kmph)

1. As per the given graph in question , we can see

 Time = 5 hours. 2

Distance = 120 km
 ∴ Speed = Distance Time

##### Correct Option: B

As per the given graph in question , we can see

 Time = 5 hours. 2

Distance = 120 km
 ∴ Speed = Distance Time

 ∴ Speed of scooterist = 120 × 2 = 48 kmph 5

1. At what time did the motorist meet the scooterist?

1. According to given graph in question , we can see that both the lines intersect when time is 10 : 30 a.m.

##### Correct Option: A

According to given graph in question , we can see that both the lines intersect when time is 10 : 30 a.m.
Hence , the motorist meet the scooterist at time 10 : 30 a.m.

Direction: The graph given here shows a car following the linear path with uniform speed. Study the graph and answer the questions.

1. The car covers a distance of 15 kilometres in

1. Given that , distance = 15 kilometres
As we know that ,

 Time taken = Distance Speed

##### Correct Option: D

Given that , distance = 15 kilometres
As we know that ,

 Time taken = Distance Speed

 Time taken = 15 = 2 1 hours. 6 2

1. The distance travelled by the car in 4.5 hours is

1. From the given graph in question ,
Here , Speed = 6 kmph , Time = 4.5 hour ( given )
We know that , Required distance = Speed × Time

##### Correct Option: A

From the given graph in question ,
Here , Speed = 6 kmph , Time = 4.5 hour ( given )
We know that , Required distance = Speed × Time
Required distance = 6 × 4.5 = 27 km

1. The speed of the car (in metres per minute) is

1. According to given graph in question ,
Speed = 6 kmph
We convert kmph into metre per minute

##### Correct Option: B

According to given graph in question ,
Speed = 6 kmph
We convert kmph into metre per minute

 Speed = 6 × 1000 m/min. = = 100m/min. 60
