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
Well it would just be 54 since you just need to move the decimal over by 1.
So 5.4x10= 54
