Question

Mike hiked to a lake in 5.5 hours at an average rate of 4 1/5 miles per hour. Pedro hiked the same distance at a rate of 4 3/5 miles per hour. How long did it take Pedro to reach the lake? Round to the hundredths place.

Answer 1

Answer:

5.02 hours

Step-by-step explanation:

d = r * t

they each hiked same distance

mike: d= 5.5 * 4.2, which equals 23.1

pedro: d = 4.6 * rate

23.1 = 4.6r

r = 5.02 hours

Answer 2

Answer:

Step-by-step explanation:

mike hiked to the lake

5.5 h with an average rate 4 1/5 miles per hour

4 1/5=21/5 miles per hour= 4.2 miles per hour

Mike hiked 5.5*4.2=23.10 miles

Pedro hiked 5.5 hours at a rate of 23/5 miles per hour or 4.6 miles per hour

Pedro hiked the same distance, 23.10 miles at an average of 4.6 miles per hour

23.10/4.6=5.02 hours
