Add up the length of all 4 sides
Answer:
He walks 150 km in 2.5 hours.
Step-by-step explanation:
From 9:30 a.m. to noon, it's 2.5 hours.
distance = speed * time
distance = 60 km/h * 2.5 h
distance = 150 km
Answer: He walks 150 km in 2.5 hours.
Answer:
0.6 km/hr
Step-by-step explanation:
Speed downstream: 13/5= 2.6 km/hr
Speed upstream: 7/5= 1.4 km/hr
Therefore, Velocity of current is: 1/2 (2.6-1.4) km/hr = 1/2(1.2) km/hr
Answer:
8.8 gallons left in the gas tank.
Step-by-step explanation:
180 x 0.04 = 7.2
16 - 7.2 = 8.8
Answer:
x=160°
since the sum of angles of the shape measures 540°
by summing up the values, we have
3x=480 divide both sides by 3
x=160°
