Answer:
230 mph in 2 hours
Step-by-step explanation:
first i found out how many miles does the train travel in one hour
460 miles ÷ 4 hours
= 115 mph / 115 miles in one hour
the question asks what was the speed of the train when it completed half the distance
half the distance = 1/2 of 460 =230 miles
230 miles is half the distance of the trip
& we know this is correct because earlier we found out that the train travels 115 miles in one hour & in 2 hours it travels 230 miles
115×2=230.
the one thing that i dont quite know is if you say the train is traveling 115 mph or 230 miles in 2 hours .im not sure of tnat .
