Answer:
Total distance covered: 60x8 = 480
Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.
initial velocity : 60 km/hr.
Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.
Step-by-step explanation:
So 2 weeks mean
250x 2= 500
Then .50 per mile so 500 miles mean
.50 x 500= 250
In total it will be
500+250= 750
Answer:
you need to simplify them like 2n+6 simplifird if 2.(n+3)
Step-by-step explanation:
Step-by-step explanation:
2x+8=2x+5
2x-2x=15-8
0x=7
