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.
A integer for -4 would be +4
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
The answer is 4/7................
