Bernardo travels the same distance at 25mph as he does at 50mph. However, since 25mph is only half of 50 mph, he must travel twice as long at 25mph. If you call the time he traveled 50mph "t", then
<span>t+2t=3 </span>
<span>3t=3 </span>
<span>t=1 </span>
<span>This means he traveled 1 hour at 50mph. In this time, he traveled 50 miles. He traveled the same distance at 25mph, so his total distance was </span>
<span>50miles+50miles=100miles </span>
<span>so the round trip was 100 miles.</span>
Answer:
x = 13y + 0.625
Step-by-step explanation:
4(2x - 3y) = y + 5
8x - 12y = y + 5
8x = y + 5 + 12y
8x = 5 + 13y
8x ÷ 8 = 5 + 13y ÷ 8
x = 5 + 13y ÷ 8
x= 13y + 5 ÷8
x = 13y + 0.625

Answer:
1) It is given that line AB is tangent to the circle at A.
∴ ∠CAB = 90º (Tangent at any point of a circle is perpendicular to the radius throught the point of contact)
Thus, the measure of ∠CAB is 90º.
