Question

The distance-time graph of an object moving with uniform speed is given below. Calculate the speed of the object.

• A. 1 m/s
  
• B. $\frac{1}{30}$ m/s
• C. $\frac{1}{60}$ m/s
  
• D. $\frac{1}{10}$ m/s

Answer 1

The correct option is C $\frac{1}{60}$ m/s


As the object is moving with uniform speed, we can calculate the $Speed=\frac{dis\tan cetravelled}{timetaken}=\frac{(30-20)m}{\left(\right(30-20)\times 60)s}=\frac{1}{60}m/s$
