The distance traveled by Mr.Nersin = 4 miles
The time for which Mr.Nersin rode first = 1/2 hour
The time for which Mr.Nersin rode after a short rest = 1/10 hour
Then
The total time for which Mr.Nersin rode = (1/2) + (1/10) hour
= (5 + 1)/10 hour
= 6/10 hour
= 3/5 hour
So
Average speed of Mr. Nersin = Distance traveled / Time taken
= 4/(3/5) miles/hour
= (4 * 5)/3 miles/hour
= 20/3 miles/hour
= 6 2/3 miles/hour
= 6.67 miles per hour
So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.
Answer:
x=8,9
Step-by-step explanation:
x^2-17x+72=0
(x-8)(x-9)=0
x=8,9

=3.5
Answer:
C
Step-by-step explanation:
With the filled in point means equal to but everything from there is less than. So the first part is equal to or less than 1. The second part is not equal with the open point so everything is greater than 1.
