Liam biked for 3 hours at a speed of 8 mph and then walked the remaining part of his way at a speed of 3 mph. If the total dista
nce he covered was 30 miles, how much time did he walk?
1 answer:
Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours

Answer:
<h2>R-{5}</h2>
Step-by-step explanation:
f(x)=x²-25=(x-5)(x+5)
g(x)=x-5
(f/g)(x)=<em>(x-5)</em>(x+5)/<em>(x-5)</em>=x+5; for x≠5
D=R-{5}
Answer:
D because if you add 10 to negative ten the cancel out and make 0
Step-by-step explanation:
The answer is B.
Since ΔQRS ~ ΔXYZ, the value of tan(Q) is :
- ∠Q = ∠X
- tan(Q) = tan(X)
- tan(X) = 3/4
- tan(Q) = 3/4
Multiply both sides by 2
(2) 18 = x/2 (2)
the /2 (2) gets canceled out
so it's 36= x
