Answer:
50 km/hr
Step-by-step explanation:
D = RT
Time for first part of trip = 80/60 = 4/3 hr.
Time for second part of trip = 20/30 = 2/3 hr.
total time for entire trip = 4/3 + 2/3 = 6/3 = 2 hr.
Total distance = 100 km
Average rate of speed for entire trip = 100/2 = 50 km/hr
Answer:
8(1/x) = 4(1/10)
Step-by-step explanation:
lets say the number is x
eight times the reciprocal of a number equals 4 times the reciprocal of 10
8 * 1//x = 4 * 1/10
8/x = 4/10 , cross multiply
4x =8*10, divide both sides by 4
x= 80/4
x= 20
Answer:
y = 3/5x + 3
Step-by-step explanation:
→ Write down in y = mx + c
y = 3/5x + c
→ Substitute in coordinates
0 = -3 + c
→ Find c
c = 3
→ Rewrite
y = 3/5x + 3
