Question

if a car travels 120 miles in 4 hours. what is its speed per hour

Answer 1

Answer:

v = 30 km/h

Step-by-step explanation:

Given that,

Distance covered by a car, d = 120 miles

Time, t = 4 hours

We need to find the speed of the car. The speed of an object is equal to the distance covered divided by the time taken. It can be given by :

$v=\dfrac{d}{t}\\\\v=\dfrac{120\ \text{miles}}{4\ \text{hour}}\\\\v=30\ \text{mph}$

So, the speed of the car is 30 km/h.
