Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
20 degrees. i have a protractor, and its really helpful! you should use one.
Answer:
87.92
In this case we're trying to find circumference
Formula: c = pi×d
The problem says to use 3.14 for pi
c = 3.14 × 28 = 87.92
The answer is 414,832,917
Answer:
148, 32, 32
148, 148, 323
32, 148
Step-by-step explanation:
m<1 = m<4 = m<5 = m< 8 = 180 - 32 = 148 degrees
m<2= m<3 = m<6 = m<7 = 32 degrees
7x+18 = 2x+28
5x = 10
x=2
2*2 +28 = 32
