Answer: 106 km/h,2.5 hr
Step-by-step explanation:
Given
The train travels 315 km in the same time car travels 265 km
The average speed of the train is 20 kmph faster than car
Suppose, speed of the car is v and it travels 265 km in t hours
Time taken to travel is
It will be will 86 first u add the 2 numbers together and then u get 94 then u do 180 minus 180 and u get 86
Mark as brainy
If you put them together, +2.5y and -2.5y neutralize themselves while 5x and 3x become 8x.
2.5y + 3x = 27
5x – 2.5y = 5
8x = 32
x = 4
2.5y + 3x4 = 27
2.5y + 12 = 27
2.5y = 27-12
2.5y = 15
y = 15/2.5
y = 6
X = 4
Y = 6
Answer:
19 minutes
Step-by-step explanation:
cost = .45+.36m
If we take 6.93 minus .45 for the minute, we get 6.48. We take 6.48 and divide it by .36 for each additional minute, which is 18. We take the 18 and add one more minute to it since .45 was covered for the first minute.
