Question

A car travels at a speed of s miles per hour. It covers 126 miles in 3 hours. The equation that can be used to find the value of s is × s = . The speed of the car is miles per hour.

Answer 1

the equation is speed = distance divided by time

speed = 126 miles / 3 hours

speed = 42 miles per hour

Answer 2

Answer:

The speed of the car is 42 miles per hour.

Step-by-step explanation:

Given that,

The distance covered by the car, d = 126 miles

Time taken by the car, t = 3 hours

Let v is the speed of the car. The total distance covered divided by total time taken is called the speed of the car. Mathematically, it is given by :

$v=\dfrac{d}{t}$

$v=\dfrac{126\ miles}{3\ hour}$

v = 42 miles/hour

So, the speed of the car is 42 miles per hour. Hence, this is the required solution.
