Question

An object is moving at a speed of 5 kilometers every 4.5 hours. Express this speed miles per minute. Round your answer to the nearest hundredth. Someone please help me I’m struggling with this one

Answer 1

speed is 0.01 miles per minute

Explanation:

We know speed = distance/time

since we need speed in miles per minute we need to convert KM into miles

and hours in minutes

--------------------------------------------------------

distance = 5 km

1 km = 0.621371 miles

5KM = 5*0.621371 miles = 3.10686 miles = 3.12 miles(rounded to nearest hundredth)

1 hour = 60 minutes

4.5 hours = 4.5*60 minutes = 270 minutes

speed = distance in KM/time in minutes = 3.12 miles/270 minutes

speed = 0.012 miles per minute

rounding the answer to the nearest hundredth

speed is 0.01 miles per minute
