Answer:
34 km/h
Step-by-step explanation:
speed = distance/time
Distance = 17km
Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours
So
speed = 17/0.5
speed = 34 km/h
620.25 u calculate 7443 and divide that by 12
First you had to switch sides of equation.
Then you divide by two from both sides of equation form.
Simplify.
Next, subtract by i from both sides of equation form.
Finally, simplify by equation.
Final answer:
