An ocean liner going from country a to country b stops for a few days in country. You are on board and wish to estimate the time it will take you to get to country b. it is 3700 km from country a to country c and 6200 km from country c to country b. It took 5.1 days to reach country c from country a. What is the average velocity of the ocean liner in km/hr? how long will it take to reach country b from country c?

1. Marth

The average velocity is v = d/t. It took 5.1 days to travel 3700km from a to c. v=?

How long does it take to travel 6200km from b to c at that velocity?
v = d/t, so t = d/v. t=?

2. iya

v= d/t
3700km + 6200km/122.4 hrs = 80.88 km/hr

t=d/v
6200km/80.88km/hr = 76.66 hrs
