When lyn walks from home to school at a speed of 3 mph, it takes her 25 minutes. how long will it take her if she runs at a speed of 5 mph?

Lyn's speed is 3 miles per hour.

That is distance travelled in 60 minutes = 3 miles

So, distance travelled in 25 minutes = 3 * 25 / 60 miles

= 25/ 20 miles

= 1.25 miles

New speed of Lyn is 5 miles per hour

That is, for travelling 5 miles, time required = 60 minutes

So, for travelling 1.25 miles, time required = 60 * 1.25 / 5 minutes

= 60/ 4 minutes

= 15 minutes.

It will take her 15 minutes, if she runs at a speed of 5 mph.

Hope this helps ..!!

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay
