Answer:
Write a time equation, time = dist/speed
:
go time + return time = total time
d%2F16 + d%2F15 = 7.75 hrs
multiply equation by the least common multiple 240, cncel the denominators:
15d + 16d = 240(7.75)
31d = 1860
d = 1860/31
d = 60 km one way
total dist = 120 km
:
Check this, find the actual time each way
60/16 = 3.75 hrs
60/15 = 4 hrs
-----------------
total time 7.75 hrs
Step-by-step explanation:
Answer:
x = 78° , y = 115°
Step-by-step explanation:
The angle adjacent to x on the left side is corresponding to 102° , then
x = 180° - 102° = 78°
----------------------------------------
y and 115° are corresponding angles and congruent, then
y = 115°
Answer:
150 seconds< 3 minutes
Step-by-step explanation:
a minute is 60 seconds; 60×3 =180
180 seconds is greater than 150 seconds
Answer:
<h2>4 p.m.</h2>
Step-by-step explanation:
We know that a day contains 24 hours in total.
The time already passed will be represented by 
.
The remaining time would be 
, becasye half of what has already passed remains until the end of the day.
Basically, the sum of these two expression gives 24 hours in total.
Therefore, the actual time is 4 p.m.
