Question

Mark walks 1/2 miles in 3/4 of an hour what is the unit rate per hours

Answer 1

`unit \: rate = (distance)/(time) \\`

substitute:

`unit \: rate = (( (1)/(2) ))/( ( (3)/(4)) ) \\ \\ = (1)/(2) / (3)/(4) \\ \\ = (1)/(2) * (4)/(3) \\ \\ = (4)/(6) \\ \\ = { \underline{ \: \: (2)/(3) \: \: miles \: per \: hour \: \: }}`
