Question

The speed time graph of a car is given here. Using the data in the graph calculate the total distance covered by the car. 30 F 25 E 20 15 C speed ( in m/ s) 10 B 5 1 a 0 10 20 30 40 50 time (in s) (a) 1250 m (6) 875 m (c) 1500 m (d) 870 m please explain me step by step​

Answer 1

Answer:

(a) 1250m

the car speed

Step-by-step explanation:

ANSWER

Answer 2

Answer:

hope it is helpful

Step-by-step explanation:

The total number of divisions on horizontal axis for 2 s is 5.

The total number of divisions on vertical axis for 2 m/s is 3.

The total displacement of the car during these two seconds will be given as the area under all these squares.

The area under the (3×5) squares is given as:

A

15

=2×2 = 4

So, the area under one small square is :

A

1

=

15

4

Now, the area under the graph for 4 sec is:

the number of squares under the graph is :

n=57 small squares + 6 half small squares

So, total number of squares =60.

So, the distance traveled by the car is the area under the curve.

S=60×

15

4

S=16 m
