Question

Tabitha is riding her bike at 27 ft/sec.  Franklin is riding his bike at 17 mph.  Who is going faster?

gorv · Answer

we need to convert the unit of speed

gorv · Answer

1mile=5280 feet

gorv · Answer

and for converting hour in second divide by 3600

gorv · Answer

$$\frac{ 5280*17 }{ 3600}=franklin speed$$

gorv · Answer

solve it and compare

anonymous · Answer

so multiply by 17 to get feet per hr. Then divide by 60 to get feet per minute, and again by 60 to get feet per second. Then you know Tabitha is faster.

60 mph = 88 fps
30 mph = 44 fps
15 mph = 22 fps
