Answer:
Average speed of Elain = 60 km/h
Explanation:
Total Distance covered by Jack = 360km
Average Speed of Jack = 80 km/h
Time taken by Jack to complete his journey = Distance / Average speed = 360 km / 80 km/h
Time taken by Jack to complete his journey = 4.5 hours
As it is given the both Jack and Elain travelled the same amount of distance:
Total distance travelled by Elain = 360 km
It is given that Elain took 1.5 hourse more than Jack to cover the distance, so Time taken by Elain to cover the distance is = 4.5 hours + 1.5 hours = 6 hours
Average speed of Elain = Distance/ time = 360 km / 6 hours
Average speed of Elain = 60 km/h
On a map showing temperature distributions, the lines that connect points of equal or same temperature are called isotherm. These are also known as contour lines and are usually presented based on a given date or time on a geographic map.

Answer:
The horizontal distance traveled by the rock from the wall after 2 seconds is 6m.
Explanation:
Given;
initial speed of the rock, u = 3 m/s
height of the wall, h = 25 m
time of travel, t = 2 seconds
The horizontal distance is determined as follows;
X = ut + ¹/₂gt²
where;
g is acceleration due to gravity, horizontal distance is not affected by gravity, g = 0
X = ut
X = 3 x 2
X = 6 m
Therefore, the horizontal distance traveled by the rock from the wall after 2 seconds is 6m.
