Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 =
; y = 20 sin 45 ; y= 14.14 miles
cos 45 =
; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
=
+ 
=
+ 
= 3131.08
= 
z = 55.96 miles

Answer:
8pi feet per second
Or, 25.1 feet per second (3 sf)
Step-by-step explanation:
C = 2pi×r
dC/dr = 2pi
dC/dt = dC/dr × dr/dt
= 2pi × 4 = 8pi feet per second
dC/dt = 25.1327412287
