Question

A scientists studied the migration pattern of two types of whales.

The humpback whale traveled 2,240 miles in 28 days.
The gray whale traveled 2,368 miles in 32 days.
if the humpback whale had traveled at the same rate for 32 days, how many more miles would they have traveled than then the gray whales?

Answer 1

humpback = 2240/28 = 80miles/ day
80*32 = 2560 miles
2560 - 2368 = 192 miles

Answer 2

If the humpback whale is travelling 2240 miles in 28 days it's traveling 80 miles/day
so 32 days would be 80×32=2560
and 2560-2368= 192
So if the humpback were to travel for 32 days it would travel 192 miles more than the grey whale
