Question

A car Is traveling at a speed of 90 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers will
the car travel in 2 minutes? Do not round your answers.

Answer 1

$\huge\boxed{\boxed{\bold{1.5\ \bftext{km/min}}}\ \boxed{\bold{3\ \bftext{km}}}}$

$\hrulefill$

To convert from kilometers per hour to kilometers per minute, we simply divide by $60$ as there are $60$ minutes in an hour.

$\frac{90}{60}=\frac{90\div30}{60\div30}=\frac{3}{2}=\large\boxed{1.5}$

To find how far the car will travel in a certain time, just multiply the speed by the time.

$1.5\ \text{km/min}*2\ \text{min}$

$\large\boxed{3\ \text{km}}$
