Question

Pacific gray whales migrate annually from the waters near Alaska to the waters near Baja California, Mexico and back. The whales travel a distance of about 5000 mi each way at an average rate of 91 miles per day. About how many days does it take the whales to migrate one way?

Answer 1

$Given \: average \: rate \: of \: migration \\of \: Pacific \:gray \: Whale \: (s) = 91 \: miles \:per \:day$

$Total \: distance (d) = 5000 \: miles$

$\red{ Number \: of \: days \: to \: migration }\\= \frac{s}{d} \\= \frac{5000}{91} \\= 54.94 \\\approx 55 \:days$

Therefore.,

$\red{ Number \: of \: days \: to \: migration }\\\green { = 55 \:days }$
