Question

The snail moved 6 inches in 120 minutes. What was the average speed of the snail in inches per minute?​

Answer 1

`(1)/(20)` of an Inch per minute

Explanation:

Speed = Distance ÷ Time

So....

6 ÷ 120 = 0.05 or
`(1)/(20)`

Also by process of elimination

`(1)/(2)` of an inch per min would complete 6 inches in 12 min.

2 inches per min would complete 6 inches in 3 min

20 inches per minute would complete 6 inches in a few seconds.

Answer 2

Option A) Speed = 1/20 of an inch per minute

Explanation:

Given:

Distance = 6 inches

Time = 120 mins

Required:

Average Speed = ?

Formula:

Average Speed = Total Distance Covered / Total Time Taken

Solution:

Speed = 6/120

Speed = 1/20 of an inch per minute
