Question

An object travelling along a straight path covers 35 m distance in 4 seconds. In next 6
seconds, it covers 50 m distance. What is the average speed of the object?
(1) 3.5 m/s (2) 4.5 m/s (3) 7.5 m/s (4) 8.5 m/s

Answer 1

Answer:

option 4) is correct 8.5m/s

Explanation:

We have

average velocity= Total distance/total time

= (35m+50m)/ (4s+6s)

= 85m/10s

= 8.5m/s

Answer 2

Given,

• An object travelling along a straight path covers 35 m distance in 4 seconds. In next 6 seconds, it covers 50 m distance. What is the average speed of the object

To Find,

• Average speed

Answer :-

• According to the question

it is given that,

• Distance covered in 1st case, d¹ = 35m
• Time taken in 1st case, t¹ = 4s
• Distance covered in 2nd case, d² = 50m
• Time taken in 2nd case, t² = 6

we have to calculate average speed of the object

Average speed is calculated by the sum of total distance covered divided by the total time taken

• Average speed = total distance / total time taken

substitute the value we get

• Average speed = d¹ + d² / t¹ + t²
• " " = 35 + 50 /4 + 6
• " " = 85 /10
• Average speed = 8.5 m/s

Hence, the average speed of the object is 8.5 m/s
