When a ferry boat is in open water it travels at a constant speed a ferry boat traveled 4 miles in 10 minutes

Complete the equation to show the relationship between the time in minutes (t) and the distance travelled in miles (d)
(T or D)=(0.4, 4, 10)(t or d)

d = t * 0.4

At this rate, how many miles will a ferry boat travel in 30 minutes

To find out how many miles a ferry boat will travel in 30 minutes, we can use the equation d = t * 0.4.

Plugging in the value of t as 30 (since we want to find out the distance traveled in 30 minutes) into the equation, we have:

d = 30 * 0.4

d = 12 miles

Therefore, a ferry boat will travel 12 miles in 30 minutes.
