Answer:
100 miles
Step-by-step explanation:
Relative Speed: 60+40=100 mph
you can think that one train is stationary,another one is 100 mph
so one hour before the train pass each other，the distance is 100 miles
-7.5x = -5.61 - 0.39
x = -6 /-7.5
x = 0.8
x= -2
MARK AS BRAINLIEST!!
total bill=1644
let he drives x kilometer
then
500*2+8*x=1644
1000+8x=1644
8x= 1644-1000
8x= 644
x= 644/8=80.5 km
V≈1570.8
Radius-10
Height- 5
The answer will be V≈1570.8
Hope this helps
