45
Step-by-step explanation:
Answer:
648 is the answer
Step-by-step explanation:
9÷1=x÷72
x=9×72( cross multply)
x=648
You can subtract 7t from both sides of the equation. This gives
... 7t -7t +3 = 8 +7t -7t
... 3 = 8 . . . . . an obvious FALSE mathematical statement
There is no value of t that will make this statement true.
The given equation has NO SOLUTION.
Answer:
1. Total distance
2. Shortest time taken
Step-by-step explanation:
Since it is a competition the distance will be the same for all participants.
therefore the information need is
1. The total distance of the competition
2. The time taken by each participant to complete the race
The winning speed is the speed is given as the distance covered in the shortest possible time.
hence the winning speed is expressed as
winning speed= distance/short time taken
