Question

A balloon-powered car rolls across the floor at a speed of 0.711 m/s. How long does it take to cover 8.25 m?

Answer 1

Time = 11.60 seconds.

Step-by-step explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

`Speed = (distance)/(time)`

Given the following data;

Speed = 0.711m/s

Distance = 8.25m

To find the time;

Making time the subject of formula, we have;

`Time = (distance)/(speed)`

Substituting into the equation, we have;

`Time = (8.25)/(0.711)`

Time = 11.60 secs.
