Answer:
Suman 37 km/hr
Narayan 43 km/hr
(extremely sorry if this is wrong!!)
Step-by-step explanation:
We can use the formula distance divided by time is speed.
480/6 = 80.
Their speeds must add up to 80 km/hour
Lets set suman as a variable, lets say s.
Narayan has a speed 6 more than suman so we say 6+s
6+s+s = 80
subtract 6 from both sides
s+s = 74
add like terms
s+s = 2s
2s = 74
divide both sides by 2.
74/2=37
s=37
Suman's speed is 37 km/hr.
Narayan's speed would be 6 more than Suman's so we do 6+37
which makes 43 km/hr
Answer:
$33
Step-by-step explanation:
c = price of cheese; s = price of sausage
3c + 3s = $36
s = c - 2
3c + 3(c - 2) = 36
2c - 2 = 12
c = $ 7
s = 7 - 2 = $ 5
Therefore, price of 4 lb of cheese and 1 lb of sausage is 4c + 1s = $28 + $5 = $33
