Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no wind.

6.5 mph

Step-by-step explanation:

Given that :

Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no

Wind speed = 2mph

Let time taken to skateboard = t

Speed = distance / time

Distance of 3.375miles against 2 mph wind

Let skate speed = x

skate speed - wind speed=

(3.375 miles / t) + 2mph = x - - - (1)

Distance of 6.375miles with 2 mph wind

(6.375 miles / t) - 2 mph = x - - - - (2)

Equate (1) and (2)

(6.375/ t) - 2 = (3.375/ t) + 2

(6.375 - 3.375) / t = 2 + 2

3 / t = 4

3 = 4t

t = 3/4

t = 0.75

Hence, speed without wind will be :

(3.375 miles / 0.75) + 2mph = x

4.5mph + 2mph = 6.5 mph

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
