Question

Steve cycled 35 miles in 2 1⁄2 hours. What is the average speed that Steve traveled?

Answer 1

35 miles in 2.5 hours so 35/2.5 gives you miles per hour.

35/2.5 = 14 m/hr

Answer 2

       /             \  
     /  distance  \               speed, distance and time triangle
   /          '           \
 /speed   '     time \
-----------------------

speed = distance divided by time
               
             (35miles)                 (2 1/2 hrs =  150 mins) 

35 divided by 150 = 0.23

average speed = 0.23
