Question

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

Answer 1

we need to convert the unit of speed

Answer 2

1mile=5280 feet

Answer 3

and for converting hour in second divide by 3600

Answer 4

\[\frac{ 5280*17 }{ 3600}=franklin speed\]

Answer 5

solve it and compare

Answer 6

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.

Answer 7

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

You don't ALWAYS have to calculate things exactly. You should ALWAYS show YOUR work.

Answer 8

multiply by 5280 to get feet /hr
thn by 60 to get feet/ min
thn by 60 to get ft/sec

Answer 9

thanks you so much .
