Answer:

correct answer is option D

Step-by-step explanation:

assume the speed of the unicorn for the first time to cover 50 mile be 'x'

we know,

distance = speed × time

    50  =  x  × time

     t₁ = 50 / x...............................(1)

when unicorn travel 300 mile with speed of '3x'

distance = speed × time

300  = 3 x  × time

    t₂ = 100/ x...............................(2)

dividing equation (2)/(1)

\dfrac{t_2}{t_1}  =  \dfrac{100/x}{50/x}

    t₂ = 2 × t₁

hence, the time will be twice the first one.

correct answer is option D

Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours. What is Rachel's unit walking rate in miles per
anyanavicka [17]

Answer:

a) 2 1/8 miles per hour

b) 8/17 hours per mile

Step-by-step explanation:

To find the rate in mile per hour, divide miles by hours:

(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = 17/8 mi/h = 2 1/8 mi/h

__

To find the rate in hours per mile, invert that number:

1/(17/8 mi/h) = 1/((17 mi)/(8 h)) = (8 h)/(17 mi) = 8/17 h/mi
