Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
Answer:
C) A rhombus has four side that are the same length.
Step-by-step explanation:
Given:
A rectangle has a length of 20 cm and a width of 15 cm.
Length = 20 cm
Width = 15 cm
We need to explain why the rectangle is NOT a rhombus.
Now according to properties of Rhombus which are given below;
⇒All sides have equal length
⇒Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram).
⇒The altitude is the distance at right angles to two sides
⇒And the diagonals of a rhombus bisect each other at right angles.
Since size of rectangle are length is 20 cm and width is 15 cm hence it is not a rhombus as Rhombus have all sides equal.
Hence Option C) A rhombus has four side that are the same length.
28 is 2*2*7, so 2 and 7 are the primer factors of 28
The second one is highlights the third one is perception and the last one is value
