Answer:
approximately 72.35 minutes
Step-by-step explanation:
there are 1609.344 meters in a mile
john ran 100 meter - which would be 16.09 per mile
9.88 seconds x 16.9 = 166.97 seconds per mile
166.97 seconds x 26 miles = 4341.22 seconds
4341.22 seconds / 60 = 72.35 minutes
Answer:
26 miles * 5280 ft/ 1 mile
Step-by-step explanation:
We know there are 5280 ft in 1 mile
26 miles * 5280 ft/ 1 mile
Answer:
Dulcina's collection has 57 pins
Eva's collection has 25 pins
Step-by-step explanation:
first we are going to represent the relation of pins by means of an equation
d = Dulcina
e = Eva
e + d = 82
and now we represent the relation of the collections of each one
d = e + 32
having the 2 equations we can replace the d by (e + 32) and place it in the other equation
e + d = 82
e + (e + 32) = 82
2e + 32 = 82
2e = 82 - 32
2e = 50
e = 25
Now we replace e with 25 in the second equation and get the value of d
d = e + 32
d = 25 + 32
d = 57
