What is the speed of a car that travels a distance of 520 kilometers in 12 hours? 0.43 km/hr 0.023 km/hr 62.4 kmhr 43 km/hr

The correct answer would be 43 km/hr.

Speed is defined as the rate at which a person or a thing is moving.

It can be calculated by dividing total distance traveled by the total time taken to cover that distance.

Speed = Distance / time

It is provided that a car traveled 520 kilometers in 12 hours.

So, the distance = 520 kilometers

Time = 12 hours

Speed = 520/12 kilometers per hour

= 43.33 kilometers per hour.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
