Question

If I was going 65 miles mph an my destination was 20 miles away how long would it take me to get there? Please show your math or calculations.

Answer 1

Another way to figure it:

60 mph speed is equivalent 1 mile per minute.

60 mph\ 65 mph (your speed)= .92 minutes per mile.

.92x60 seconds =55.2 seconds per mile traveled.

20 miles X 55.2 seconds =1104 seconds

1104 seconds/60 seconds per minute= 18.4 minutes

18.4 minutes = 18 minutes, 24 seconds

Next time, do your own math!!:)

P.S...I hope the "thumbs down" didn't come from you Cat, 'cuz you're wrong:)  Let me rephrase, you're not wrong, yours is a "shorthand" formula; while although correct in a mathematical sense, is less acurate.

Consider going 60 mph..that's 60 miles in an hour, that's 1 mile per minute correct?

According to your calculation of D=RT

20 miles (distance)=60T

20/60=.33

.33 hours=.33X 60 minutes=19.8 minutes

How can the answer be 19.8 minutes when we have already established a speed of 60 mph is equal to 1 mile per minute?

If I'm missing something, please explain...?

Answer 2

divide 20 by 65

Answer 3

1 ------ 65

x  ----  20

To solve  you multiply 20 by one and divide between 65

then ...   0.3 hours  ...

if you want minutes multiply by 60 ... then   will be 18.45 minutes.

Answer 4

I would say that the time taken depends on the traffic as well as your speed. The average speed for commuting between two places where there is in-town traffic can be very low, but for an average 20 mile run in moderate traffic it might delay you by up to 100% (only!) and double the journey time. Junctions and traffic-lights are the work of the devil (or of the bountiful municipality, if you happen to need to change direction)!

Answer 5

Use the formula D=rt

20=65t

20/65=t

t=.31hours

.31hours=18.6minutes               (.31*60)
