Explanation:
To calculate the value of 'x', we need to solve each function happening inthe equation.
The equation provided to us is 
To solve this, we will multiply 4x with 2 and then subtract the like terms and finally, we evaluate the value of 'x'.
Hence, the value of x will be -6.
you need to use hours to make it easy to convert to m/s. Change 15 minutes to hours
Note distance is in km so change the time to hours to get km/hour
1 hour = 60mins so 15 minutes will be 0.25 hours
10/0.25 = 40 km/ hour
To change that to m/second, change km to meters and hour to second
it will be (40x1000) meters /3600seconds
11.1111 m/s
