A turtle walks 78 of a mile in 50 minutes. What is the unit rate when the turtle’s speed is expressed in miles per hour?

Answer 1

A turtle walks 7/8 mile in 50 minutes.

Convert 1 hour to minutes and you get 60 minutes.

50/60 = 5/6. The turtle walks 7/8 mile in 5/6 hour

$\frac{\frac{7}{8} }{\frac{5}{6} } = 21/20$

The turtle walks 21/20 or 1.05 miles per hour.

Answer 2

Answer:

1 1/25 miles

Step-by-step explanation:

create a proportion from distance / time equals distance / time

r = rate

(7/8 ÷ 50) = (r ÷ 60)    *60 for 60 minutes (1 hour)

cross-multiply to get:

420/8 = 50r

52.5 = 50 r

r = 1.04 which is 1 4/100 or 1 1/25 miles
