Question

Help pls do the last two all work and last two questions

Answer 1

d1 = 15 miles

t1 = 1 hour

d2 = 25 miles

t2 = 2 hours

d = 15 + 25 = 40 miles

t = 1 + 2 = 3 hours

$avg. \: speed \: = \: \frac{total \: distance}{total \: time}$

$avg. \: speed \: = \frac{40}{3}$

$avg. \: speed \: = 13.33mi \: hr ^{ - 1}$
