Question

You sit in a car that is moving at an average speed of 86.4 km/h. During the 3.3 s that you glance out the window, how far has the car traveled?

Answer 1

Answer:

79.2m

Explanation:

v(velocity)=86.4km/h=24m/s

t(time)=3.3s

1. s=vt=79.2m

Answer 2

Given: Car is moving at an average speed at an average speed of 86.4 km/h.

To find: Distance travelled in 3.3 seconds at this average speed

Explanation: Speed of car= 86.4 km/h

Since time is given in seconds, we need to convert km/h to m/s. For converting km/h to m/s we need to divide the value given in km/h by 3.6

86.4 km/h= 86.4/3.6 m/s

= 24 m/s

Distance travelled= Velocity* Time

= 24 * 3.3

= 79.2 m

Therefore, the distance travelled in 3.3 second at the constant speed of 86.4 km/h is 79.2 m.
