On a map, Roseville and smith town are 5 1/2 inches apart If the actual distance between the town is 16 1/2 miles, to what unit rate is the map drawn

The unit rate =  3 miles per inch.

Step-by-step explanation:

Given: Distance on map = inches inches

Actual distance =  miles miles

That means 1 inch on map =

Hence, the unit rate =  3 miles per inch.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
