The equation that relates the time, t, it takes to travel a given distance, d is d = rt 
<h3>What is Speed?</h3>
This is a scalar quantity and can be defined as  the magnitude of the rate of change of its position with time.
d = rt 
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t =  d/r
This is why it was chosen as the most appropriate choice.

Answer:
a. 2^3
b. 3^4
c. 4^3 × 5^2
d. 9^4 × 7^2
Step-by-step explanation:
The following equations are given 
a. 2 × 2× 2
b. 3 × 3 × 3 × 3 
c. 4 × 4 × 4 × 5 × 5
d. 9 × 7 × 9 × 9 × 7 × 9
We need to find the index notation for the above equations 
a. 2^3
b. 3^4
c. 4^3 × 5^2
d. 9^4 × 7^2
In this way it should be done
