You provide a dog-walking service, and you report to the owners on the amount of exercise their dogs get on the walks. You walked Fifi for 35 minutes and went 1.5 miles. What speed can you report to the owner.A. 7/8 mph
B. 35/60 mph
C. 53/60 mph
D. 2 4/7 mph
E. 2 7/8 mph

Answers

Answer 1
Answer: So we want the speed of the dog which the equation got speed is;

v=d/t so using the given values we have we get;

v=1.5miles/35min but we need min in hours so by doing simple unit conversion we get;

35min(1hr/60min)=.58333hrs so now we have;

v=1.5miles/.5833hrs= 2.57mph

But to get it in form of your answer choices we can just use common sense and rule out all choices but D and E and E is too fast as it is 2.875mph and 2-4/7=2.571 which matches our answer.

So the answer is D 2 4/7mph

Hope this helped you out some and if you have any questions please feel free to ask.
Thank you

At the start of the day there are 78 boxes of DVDs in a warehouse. Each box has 116 DVDs. Then 19 of the boxes are shipped. Now how many DVDs are left in the warehouse?

Answers

Answer:

6844DVDs

Step-by-step explanation:

At the start of the day, there are 78boxes in the warehouse and each box contains 116DVDs, the total number of DVDs in the warehouse will be total number of DVDs per box × number of DVDs in each box;

No of DVDs in the warehouse = 78×116

= 9048DVDs

If 19boxes of DVD were shipped, the total number of DVDs shipped will be 19×116(remember there are 116DVDs in a box)

= 2204DVDs

To calculate the amount of DVDs left in the House, we will use the expression;

Total number of DVDs in the warehouse - total number of DVDs shipped

= 9048-2204

= 6844DVDs
2,204 dvds are left since 19 times 116 is 2,204
