Question

Ella traveled by train to visit her friend.

• It took 3 hours for Ella to reach her destination.
• The train averaged a speed of 100 miles per hour.
Enter an equation to express the distance, d, Ella traveled.

Answer 1

d = st, d = 100 x 3

Explanation:

distance = speed x time

distance = 100 x 3, therefore, distance = 300, but if you just want the equation, it is d = 100 x 3 or d = st

Answer 2

Explanation:

d = 100 x 3.

d= 100n

where n = time the journey took.
