Reece and Samuel are training for a cross country meet. The ratio of miles Reece runs to miles Samuel runs is 2 to 3. If Samuel logs 81 miles, then how many miles did Reece log?

Reece log 54 miles

Step-by-step explanation:

The ratio of miles Reece runs to miles Samuel runs is 2 to 3.

Samuel logs 81 miles

the ratio 2 to 3 means that if Reece ran 2 miles Susan would run 3 miles, so Reece runs with respect to Susan is 2/3

R = Miles Reece runs

R = 2/3 * 81mi

R = 54mi

Reece log 54 miles

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.
