The average speed of the runner is 12.7 mph and 20.4 km/h
Given that the runner ran 26.2 mile in 2hr and 4 minutes, we start of by converting the time from hours and minutes into minutes and finally hours, since hours is what we need. So, we have
2hr = 120mins
+ 4 mins = 124 mins
124 mins ÷ 60 hour/mins = 2.06 hours.
This means that the runner finished the race in 2.06 hours.
If we are to find the average speed in mile per hour, we have
Average speed = distance ran ÷ time taken
Average speed = 26.2 ÷ 2.06
Average speed = 12.7 mph
From the speed in mph, we can directly convert it to km/hr by saying
1 mph = 1.609 km/h
12.7 mph = 12.7 * 1.609 = 20.4 km/hr

83x + P = 83x + Q <em>subtract 83x from both sides</em>
P = Q
The equation has no solution for P different Q (P ≠ Q).
Answer:21
Step-by-step explanation: plug in 19 and 1
1x3 is 3 plus 19 is 21
Answer: 3
Explanation:
27 = 3^3
42 = 2 x 3 x 7
So the HCF of (27,42) = 3
