Answer» Answer: 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} }Speed= time Distance
On PUTTING respective value in above equation: \mathbf{Speed= \dfrac{150}{18} }Speed= 18 150
\mathbf{Speed= \dfrac{25}{3} \ \ \ \left ( \dfrac{m}{s} \right )}Speed= 3 25
( s m
) \mathbf{Speed= 8.333 \ \ \ \left ( \dfrac{m}{s} \right )}Speed=8.333 ( s m
) His speed is 8.333 m/s. |
