Answer:
Question 7: Distance = 237.6 km
Question 8: Distance = 399.3 km
Step-by-step explanation:
Question 7:
Given:
Minimum speed (s) = 72 km/hr
Time taken (t) = 3.3 hours.
We know that, distance traveled is equal to the product of speed and time.
Therefore using distance formula, we get:
Distance = Minimum speed × Time
Distance =
Distance =
Therefore, distance traveled at this speed is 237.6 km.
Question 8:
Maximum speed (S) = 121 km/hr
Time taken (T) = 3.3 hours.
We know that, distance traveled is equal to the product of speed and time.
Therefore using distance formula, we get:
Distance = Maximum speed × Time
Distance =
Distance =
Therefore, distance traveled at this speed is 399.3 km.
Answer:
The area of the sector is
Step-by-step explanation:
we know that
The area of a complete circle (16π units^2) subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector , if the central angle is equal to 8π/5 radians
