X^2=3^2+7^2-*3*7cos52
x=6.083
7^2=3^2+6.08^2-2*3*6.08cosy
solving for y
y=94.71
An expression for “7 divided by c” is 7/c or 7 ÷ c
Answer:
36.67 [mile/hour].
Step-by-step explanation:
1) use the formula: V=S/t, where S - entire jorney, v - average speed (required to calculate), t - elapsed entire time.
2) according to the formula above S=50+60=110 miles; t= 50/40 + 1.75=1.25+1.75=3 hours.
3) after the substitutuion 110 and 3 into the formula above:
v=110/3≈36.67 miles/h.
