A jogger runs 6 miles per hour faster downhill than uphill. If the jogger can run 5 miles downhill in the same time that it take
muminat

Answer:

The speed of jogger in uphills is 4 mile per hour  

And  The speed of jogger in downhills is 10 mile per hour

Step-by-step explanation:

Given as :

The distance cover by jogger in downhill (Dd) = 5 miles

The distance cover by jogger in uphill     (Du)  = 2 miles

The time taken by jogger in downhill       (Td)  = T  hour

The time taken by jogger in uphill            (Tu)  = T hour

Let The speed of jogger in uphills            (Su)  = x mph

So ,The speed of jogger in downhills      (Sd)  =( x + 6 ) mph

∵, Time = \frac{Distance}{Speed}

So, Tu = \frac{Du}{Su}

Or, T = \frac{2}{x}   h

And Td = \frac{Dd}{Sd}

Or,   T = \frac{5}{(x + 6)}  h

∵  Time duration of both is same

∴  \frac{2}{x} = \frac{5}{(x + 6)}

Or,  2 × (x + 6) = 5x

Or,  2x + 12 = 5x

So,    12 = 3x

∴       x = \frac{12}{3} = 4 mph

And  x + 6 = 4 + 6 = 10 mph

Hence The speed of jogger in uphills is 4 mile per hour  

And      The speed of jogger in downhills is 10 mile per hour   Answer

Tickets to the dinosaurs now exhibit cost $10.50 each and come in a book of 8. how much change will kenny get from $100 if he bu
inn [45]

Answer:

Kenny will get $16 change from $100 if he buys a book of 8.


Step-by-step explanation:

Given cost of each ticket of the dinosaurs now exhibit = $10.50.

Total number of tickets = 8 tickets.

Total amount Kenny has to buy tickets = $100.

He need to buy only 8 tickets.

Total cost of 8 tickets = cost of one ticket × total number of tickets

                                    = 10.50 × 8

                                   =  $84.

Therefore cost of all 8 tickets is $84.

Kenny would left money = 100 - 84 = $16.

<h3>Therefore, Kenny will get $16 change from $100 if he buys a book of 8.</h3>
