. He rowed 3 1/2 miles in 1/2 hour.What is the average speed in miles per hour.
Rudiy27

Answer:

7 miles per hour

Step-by-step explanation:

3 1/2 miles = 7/2 miles

1/2 hours= 30 minutes

So,

In 30 mins, travelled 7/2 miles

In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles

In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.

Hence, the speed is 7 miles per hour.

Hope this helps :)

Montano1993 [528]

Simplify.
irina1246 [14]
We have,
(2y)^3 × y^-1

Simplify the term (2y)^3

= 8y^3 × y^-1

Now, multiply the terms with the same base y by adding their exponents.

Note: Using exponent product rule x^y × x^z = x^(y+z)

= 8y^{3+(-1)}
= 8y^(3-1)
= 8y^(3-1)
= 8y^2
