Question

The distance y in miles traveled by a striped marlin in x hours is shown in the graph. Each ocean creature’s distance in miles is a direct variation of the time it travels in hours. Select which ocean creature is faster than the striped marlin.

A tuna travels at a speed of 43.5 miles per hour.


A wahoo fish that travels 144 miles in 3 hours and 192 miles in 4 hours.


A swordfish whose distance y in miles is represented by the equation y=60x, where x s the number of hours.


A Mako shark whose distance y in miles is represented by the equation y=31x, where x is the number of hours.

Answer:

swordfish

Explanation:

The graph shows the marlin travels 50 miles in 1 hour, and 150 miles in 3 hours. These numbers can be compared directly to those given for the tuna (43.5 miles in 1 hour) and the wahoo fish (144 miles in 3 hours).

The speeds of the swordfish and shark are the coefficients of x in their respective equations. The swordfish travels 60 mph, so is faster than the marlin. The shark travels 31 mph, so is slower.
