What unit? I don’t see anything to help you answer.
Let you be at point A while your friend be at point B,
while you are still having lunch,
you friend travels= 27/60*75miles/h=33.75miles
Remaining Distance= 135miles-33.75miles=101.25miles
Take note here is the tricky part, for the remaining distance both you and your friend are driving towards each other,
So first,
Total speed =Adding both ur friend and ur speed= 60+75=135miles/h
Time taken to meet= 101.25miles/135miles/h=0.75h
Total hours ur friend drives= 0.75h+27/60h=1.2h
total distance ur friend drove= 1.2h * 75miles/h= 90km
for the part how far u travelled,
simply take 135miles -90miles=45miles

Distance traveled by the rocket= 1002 m
Explanation:
initial velocity= Vi=0
final velocity= V=445 m/s
time=4.5 s
Acceleration=a=99 m/s²
using kinematic equation
h= Vi t + 1/2 at²
h= 0(4.5) + 1/2 (99) (4.5)²
h=1002 m
Thus the distance traveled by the rocket= 1002 m
