Question

The car you are in is traveling 39 km/hr. How many miles have you gone in 15 minutes?

(Conversion problem)

Answer 1

6.06miles

Step-by-step explanation:

Given parameters:

Speed of the car = 39km/hr

Time = 15minutes

Unkown:

Distance in miles

Solution:

Speed is the change in distance with time.

Speed =
`(Distance )/(Time)`

We need to express our parameters in the same workable units. So we should convert the given time to hour.

60min = 1hr

15 min = 0.25hr

Therefore:

Distance = speed x time = 39km/hr x 0.25hr = 9.75km

Now convert km to miles

1.609km = 1mile

9.75km =
`(9.75 )/(1.609)` , 6.06miles
