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.
Step-by-step explanation:
Subtracting N by T
(3a2 + 2a - 5) - (2a2 + a + 6)
Subtracting like terms
a2 + a - 11
27, you need to simplify both sides of the equation to get x on one side.
