If Eli bikes at a constant speed of 15 feet per second,
which of the following is closest to how many miles
he will bike in 2 hours? (1 mile = 5.280 feet;
1 hour = 60 minutes; 1 minute = 60 seconds)
A) 0.3
B) 10.2
C) 11.0
D) 20.5

D 20.5 Miles

Explanation: First, you know Eli has a constant speed of 15 feet per second and you also know there are 60 seconds in a minute. Because of this you multiply 15x60 and get 900. You also know there are 60 minutes in an hour so you multiply the 900x60 and get 54,000. The question asks for 2 hours not 1 so you multiply 54,000x2 and get 108,000. After that all that's left to do is divide 108,000 by 5,280 because to convert from feet to miles which gives you ≈20.454545... and you can round that to 20.5 miles.

Hope that helped! :)
