Answer:

81 km

Step-by-step explanation:

Speed = distance / time

speed and time are measured in different units, thus, time has to be converted to seconds

60 second = 1 minute

90 x 60 = 5400 seconds

15 m /s = distance / 5400 seconds

distance = 81,000 metre

1000m = 1 km

81000 / 1000 = 81km

VMariaS [17]

Answer: 2

Step-by-step explanation: In order to find out the radius you first need to find out the diameter. Diameter times pie or 3.14 equals the area. So, if the area is 12.4 you need to divide 12.4 by 3.14 which gives you 3.94 which rounds up to 4. The radius is half of the diameter so divide 4 by 2 to get 2
