Acar traveling 100 miles in 2 hours has a unit rate of miles per hour.

A car traveling 100 miles in 2 hours has a unit rate of 50 miles per hour.

Solution:

A car is travelling 100 miles in 2 hours.

But we need to find out how many miles it travels in 1 hour.

This is because the question specifies miles per hour which mean the miles travelled by the vehicle every 1 hour.

To find this we need to divide 100 by 2

This gives the how many miles the car is travelling in 1 hour, that is 50 miles.

Hence the required answer is the car travels 50 miles per hour.

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.
