If a train travels 80 m/s in two hours and 20 minutes, how far has it traveled? answer in kilometers

5856 km

Step-by-step explanation:

change 2 hours 20 minutes to seconds

2  hrs * 60 minutes/1hr * 60 sec/min = 7200 sec

20 minutes * 60 sec/min = 120 sec

2 hr 20 min = 7320 seconds

80 m/s * 1 km / 1000 m = .08 km/s

distance = rate * time

distance = .080 km/s * 7320 s = 5856 km

it is part of the rising action that reveals public sentiment toward hester.

explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
