If Amanda hikes at an average speed of 2.72 miles per hour, how long will it take her to hike 6.8 miles

It will take Amanda 2 hours and 30 minutes because 2.72 is an hour and 1.36 is half an hour (30 minutes) so if you multiply 2.72 by 2 you get 5.44 then you add 1.36 and you will end up with 6.80 so the answer is 2 hours and 30 minutes.

Speed times time=distance

distance=6.8

speed=2.72

time=?

2.72 times?=6.8

divide both sides by 2.72

?=2.5

answer si 2.5 hours
