Pls answer this it’s very confusing and pls don’t lie

Work Shown:

3 & 2/5 = 3 + (2/5) = 3 + 0.4 = 3.4

Mike walked for 5.5 hours at an average rate of 3.4 mph.

His speed is r = 3.4 and the time taken is t = 5.5

Let's find the distance d

distance = rate*time

d = r*t

d = 3.4*5.5

d = 18.7

Mike traveled 18.7 miles

Pedro walked the same distance (18.7 miles) but his rate is 3.8 mph since

3 & 4/5 = 3 + (4/5) = 3 + 0.8 = 3.8

Therefore, Pedro's time is

d = r*t

d/r = t

t = d/r

t = (18.7)/(3.8)

t = 4.92105263157894 approximately

t = 4.92 hours
