the answer is going to be 6.0
Step-by-step explanation:
1.5 + 1.5 = 3
3 + 3 = 6
rate = 4 miles/hour
d=r*t distance = rate* time
d= 4*3.5
= 14 miles
I think part A is 6 miles in a hour and part B is i'm guessing 20 min is how long it would take because that's how long we take to WALK a MILE.
X=25cos10+30cos100
y=25sin10+30sin100
v=√(x^2+y^2)
α=tan(y/x)
Rounding to two decimal places in intermediate steps...
x≈19.41, y≈33.89
v≈39.05
α=60.20°
So (39.05, 60.20°)
