Hi there, to solve this problem we divide 248 miles by 4 hours. Let's begin, 248 miles ÷ 4 hours = 62. Therefore, Clara's average rate of speed was 62.
Answer:
83 mph
Step-by-step explanation:
Their combined speed is 540 mi/(3 h) = 180 mi/h. The eastbound train's speed will be half this, less half the difference: 180/2 - 14/2 = 83 mi/h.
_____
If s represents the slower train's speed, then ...
s + (s +14) = 180 . . . . the sum of the train speeds is 180 mph
2s + 14 = 180 . . . . . . .simplify
2s = 180 -14 . . . . . . . .subtract 14
s = 180/2 -14/2 = 83 . . . . divide by 2
Answer:
40078-18537=21541

Answer:
it’s D
Step-by-step explanation:
A) 6 cm, 23 cm, 11 cm
B) 10 cm, 15 cm, 24 cm
C) 22 cm, 6 cm, 6 cm
D) 15 cm, 9 cm, 24 cm
3 minutes - 2 minutes = 1 minute
30 gallons - 12 gallons = 18 gallons
it is draining at 18 gallons per minute
equation would be: y = -18x
