Answer:
T = D/S
Explanation:
Given the formula for calculating the average speed of an object as:
average speed = Distance/Time
Let average speed = S
Distance = D
Time = T
Substitute
S = D/T
Make T the subject of the formula:
From S = D/T
Cross multiply
ST = D
Divide both sides by S
ST/S = D/S
T = D/S
Hence the expression for he time T after rearrangement is T = D/S
