A cyclist travels the length of a bike path that is 225 miles long, rounded to the nearest mile. If the trip took him 5 hrs, rounded to the nearest hour, then his average speed must be between:
A. 38 and 50 mph
B. 40 and 50 mph
C. 40 and 51 mph
D. 41 and 50 mph
E. 41 and 51 mph
For Distance:
224.5 < 225 < 225.5
For Time:
4.5 < 5 < 5.5
For Speed:
Case I: \(\frac{224.5}{4.5} = 49.88\)
Case II: \(\frac{224.5}{5.5} = 40.81\)
Case III: \(\frac{225.5}{4.5} = 50.11\)
Case IV: \(\frac{225.5}{5.5} = 41\)
All these values lie between 40 and 51
Hence, option C
