A rhombus has four equal sides and does not have four 90 degree angles / sides that are perpendicular to each other. However, a rectangle does have four 90 degree angles with sides that are perpendicular.Another characteristic; a rhombus has four equal sides, while a rectangle has two pairs of congruent sides.

in short, we simply divide the whole of 45 by (7+4+3+1), and then distribute accordingly, let's do that,

$\bf \cfrac{45}{7+4+3+1}\implies \cfrac{45}{15}\implies 3 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{Stephen}{7(3)}~:~\stackrel{Marley}{4(3)}~:~\stackrel{David}{3(3)}~:~\stackrel{Katherine}{1(3)}\implies \stackrel{Stephen}{21}:\stackrel{Marley}{12}:\stackrel{David}{9}:\stackrel{Katherine}{3}$

David hikes 21/4 miles in 1/2 an hour. What is his rate in miles per hour? At this rate, how long will it take him to walk 18 mi

harkovskaia [24]

Answer:

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C) Distance = 10.5 mph × 7 hours = 73.5 miles

Step-by-step explanation:

Given as :

The distance cover by David = $\frac{21}{4}$ miles = 5.25 miles

The time taken by David = $\frac{1}{2}$ hours = 0.5 hours

Let the speed = x mile per hour

So, Distance = Speed × Time

A)or, Speed = $\frac{Distance}{Time}$

Or, Speed = $\frac{5.25}{0.5}$

∴ speed = 10.5 miles per hour

<u>B) Again The Distance cover by him = 18 miles</u>

SO, with speed 10.5 miles per hour

The Time taken by him = $\frac{Distance}{speed}$ hours

Or, Time taken by him = $\frac{18}{10.5}$ hours

∴ Time taken by him = 1.714 hours

<u>C) Again the Time taken by him = 7 hours </u>

So, Distance cover by him with speed 10.5 mph

Or, Distance = 10.5 mph × 7 hours = 73.5 miles

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C) Distance = 10.5 mph × 7 hours = 73.5 miles Answes
