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

Answer:42
Step-by-step explanation:
Question 1: h+4= how many kids in history class.
I think this cause it says to represent the # of kids in the English class with the varible h. there are 4 more kids in the history class for you just add four to the English class( h). this may be wrong tho
question 2: 57+4= 61.
you just input the 57 where the h (# of kids in English class) cause it need to figure out how many are in history and their are just four more kids. I think
also sorry if I suck at explaining things, this makes sorta sense
Answer is C. 7:42
Because the numbers from the ratio 3:18 , 18/3 is 6
And from the ratio 7:42, 42/7 is also 6
Because the difference in the ratios are the same, the ratios are equivalent
Another way is that 3:18 can be rewritten as 3/18 which is simplified to 1/6. 7:42 = 7/42 which also equals 1/6.
Both ratios simplified equal 1:6.
None of the other answers simplify to this but C.
