Question

a car is traveling 55.0 miles per hour . convert this to meters per second . one miles is equal to 1.61 km

Answer 1

55 miles/1 hour(1.61 km/1 mile)(1000 meters/1km)=88550 meters per hour
88550 meters/1 hour(1 hour/60 minutes)(1 minute/60 seconds)
=24.5972 meters per second

Answer 2

Answer : The speed of car in meters per second is 24.597 m/s

Explanation :

The conversion used from miles to kilometer is:

1 mile = 1.61 km

The conversion used from kilometer to meter is:

1 km = 1000 m

So,
`1mile=\frac{1.61km}* (1000m)/(1km)=1610m`

The conversion used from hour to second is:

1 hr = 3600 s

So,
`1mile/hr=(1610)/(3600)m/s`

As we are given the speed 55.0 miles per hour. Now we have to determine the speed in meter per second.

As,
`1mile/hr=(1610)/(3600)m/s`

So,
`55.0mile/hr=(55.0mile/hr)/(1mile/hr)* (1610)/(3600)m/s=24.597m/s`

Therefore, the speed of car in meters per second is 24.597 m/s
