See picture below. Being that you did not provide possible answers, I don't know what answer you can choose from.
Answer:
Your car is faster of course
Step-by-step explanation:
100 km would be 100000 meters. Then you would need to know that if Usain bolt ran 100 meters every 9.54 sec then in 100000 meters he would have ran 9540 seconds which is also known has 159 minutes, which is more than 1 hour so your car is faster.
B because the amount of money they earn per hour multiplied by how many hours they worked is equal to what they earned in total
North American : South American : European
9 : 5 : 2
Multiply all by 10
90 : 50 : 20
The answer is 50 South American butterflies.
