2) On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is t= d. How long will it take the airplane to travel 800 miles? Show your work 500

Answers

Answer 1

Answer:

The equation for relation of time with distance travelled is,

$t=(1)/(500)d$

Substitute 800 for d in the equation to determine the time required for travelling 800 miles.

$\begin{gathered} t=(1)/(500)\cdot800 \n =(8)/(5) \n =1.6 \end{gathered}$

So airplane take 1.6 hours to travell 800 miles.

Answer: 1.6 hrs

Marisol and Mimi walked the same distance from their school to a shopping mall. Marisol walked 2 miles per hour, while Mimi left an hour later and walked 3 miles per hour. If they reached the mall at the same time how far is the mall from their school?

Answers

Let the time in hours after Marisol starts walking be t and so the time in hours after Mimi starts walking is (t-1)
The distance walked by Marisol=speed*time=2t
Distance walked by Mimi=3(t-1)

When they've reached school they've all walked the same distance so:
3(t-1)=2t
3t-3=2t
3t-2t=3
t=3
Thus the distance from the mall to their school is 2t=2*3=6 miles
