Question

The distance travelled varies directly with time. Anthony ran 49.6 metres in 8

seconds. Write an equation for this relationship. Use let statements to define your
variables & write a conclusion statement to state your answer.

Answer 1

D = kT

Explanation:

• Let the distance travelled be D.
• Let the time taken be T.

Given the following data;

• Distance, D = 49.6 meters.
• Time, T = 8 seconds.

To write an equation for this relationship;

D = kT

Where;

• k is the constant of proportionality.

In conclusion, the distance travelled by Anthony is directly proportional to the time taken to travel that distance i.e an increase in the distance would cause an increase in the time taken to travel that distance and vice-versa.
