Answer:
2.5 hours
Step-by-step explanation:
The product of speed and time is distance. If the distance is the same, then time is inversely proportional to speed. At 60/50 = 6/5 times the speed, the return trip will take 5/6 times the time:
(5/6)(3 hours) = 2.5 hours . . . time for return trip
Answer:
<h2> 18.3</h2>
Step-by-step explanation:
from cosines theorem:
t² = 11² + 14² - 2•11•14•cos87°
t² = 121 + 196 + 308•0.05236
t² = 333.12688
t = √333.12688
t = 18.2517... ≈ 18.3
Answer:
D. 11.4 miles.
Step-by-step explanation:
Distance between the Center and the Mall = √(5^2 + 3^2) = √34.
Distance between The Park and the Center = √(4^2 + 4^2) = √32.
So the Distance between The Mall and the Park is √34 + √32
= 11.4 miles (answer).
Answer:
this question doesn't make sense. Isn't there a speed?
