Answer:
100 km/hr
Step-by-step explanation:
First Leg:
Speed = 60 km/h
Time = 30 min = 0.5 h
1st leg distance = speed x time = 60 km/hr x 0.5hr = 30 km
Second Leg:
Distance remaining = 80 km - 30 km = 50 km
Time = 30 min = 0.5 h
speed = distance / time = 50 / 0.5 = 100 km/hr
Answer:
(2a,a)
Step-by-step explanation:
We know that the longer side (the length) is twice the shorter side (the height). So the x-coordinate will be twice the highest y-coordinate. The highest y-coordinate is a, so the furthest x-coordinate will be 2a. The top right vertex lies on the same y-coordinate as the top left, so the y-coordinate will also be a.
(2a, a) is the answer.
I really hope this helps you =)
