First of all, you can convert meters to feet. Since one meter is 3.2808399 feet, this means that 2.7 meters are 2.7×3.2808399 feet, which is 8.85826772 feet.
Now, if you know that in a second you travel 8.85826772 feet, how many feet you will travel in a minute? Assuming the speed to be constant, the distance traveled in a minute will be 60 times the distance traveled in a second, so 60×8.85826772=531.4960632, which is the final answer, since now we are expressing speed with feet per minute.
In case you wondered, this is 0.26 the speed at which Usain Bolt runs his best 100 meters :)
