Question

Pete is driving down 7th street. He drives 150 meters in 18 seconds. Assuming he does not speed up or slow down, what is his speed in meters per second?

Answer 1

Given:

Pete is driving down 7th street. He drives 150 meters in 18 seconds. His speed is constant.

To Find:

What is his speed in meters per second?

Solution:

Distance travel by Pete is given as below:

Distance(D) = 150 m

Time taken by Pete to travel distance 150 m is given below:

Tome(T) = 18 s

We know the formula of speed in term of distance and time is given below:

$\mathbf{Speed= \dfrac{Distance}{time} }$

On putting respective value in above equation:

$\mathbf{Speed= \dfrac{150}{18} }$

$\mathbf{Speed= \dfrac{25}{3} \ \ \ \left ( \dfrac{m}{s} \right )}$

$\mathbf{Speed= 8.333 \ \ \ \left ( \dfrac{m}{s} \right )}$

His speed is 8.333 m/s.

Answer 2

Answer:

answer will be =8.333 m/s

Explanation:

formula of speed= distance\time

means= 150/18

=25/3

= 8.333 m/s
