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:
Cos(39) + x/17
x = 17cos(39)
x = 13.2<span>1148134</span>
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
It is B=24
Hope this helps:)
