Question

1 ½ miles in ¾ hour
find the unit rate

Answer 1

Unit rate = 2 mph

Explanation:

Distance travelled = 1½ miles =
`(3)/(2)` miles

Time taken = ¾ hours

`Unit \: rate = (distance \: travelled)/(time \: taken) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = ( (3)/(2) )/( (3)/(4) )\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (3)/(2) * (4)/(3) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \: mph (miles \: per \: hour)`
