If amanda hikes at an average speed of 2.72 mph, how long will take her to hike 6.8 miles?

3 hours and 15 minutes

goog may have it for you

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
