Question

a truck travels 10 m distance in 5 sec and 20 m distance in next 5 sec the average speed of the car is _____ m/sec​

Answer 1

Answer:

Provided that:

• A truck travels 10 metres distance in 5 seconds and 20 metres distance in next 5 seconds.

To calculate:

• Average speed

Solution:

• Average speed = 3 m/s

Using concepts:

• Total distance formula

• Total time formula

• Average speed formula

Using formulas:

• Total distance = Distance first + Distance second

• Total time = Time first + Time second

• Average speed = Total distance/Total time taken

Required solution:

~ Firstly finding total distance!

→ Total distance = Distance first + Distance second

→ Total distance = 10 m + 20 m

→ Total distance = 30 m

~ Now finding total time taken!

→ Total time = Time first + Time second

→ Total time = 5 sec + 5 sec

→ Total time = 10 seconds

~ Now finding average speed!

→ Average speed = Total distance/Total time taken

→ Average speed = 30/10

→ Average speed = 3 m/s $\:$
