A boat is cruising in a straight line at a constant speed of 2.3m/s when it is shifted into neutral. After coasting 12m the engine is engaged again, and the boat resumes cruising at the reduced constant speed of 1.3m/s.

Part A
Assuming constant acceleration while coasting, how long did it take for the boat to coast the 12m ?

Part B
What was the boat's acceleration while it was coasting?

Part C
When the boat had coasted for 6.0m , was its speed 1.8m/s , more than 1.8m/s , or less than 1.8m/s ?
