Question

Write each rate as a fraction in lowest terms
20 feet in 30 seconds

Answer 1

`= { \boxed{ \sf{ (2)/(3) }}} \: { \tt{feet/sec }}`

Answer 2

2/3

Explanation:

The basic formula is d = r * t. The units are important. Time is usually recorded as seconds. d can be feet or meters in standard form. The formula has to be rearranged to get r by itself.

r = d/ t

d = 20 feet

t = 30 seconds

r = 20 feet / 30 seconds

r = 20 ft/sec

Even though you are told not to enter the units, it is still important to recognize what they are.
