Since Krystal and Scott is heading on opposite
directions, therefore the distance between the two would be the sum of their
distances from where they left, so:
total distance (d) = distance covered by Krystal (dK) +
distance covered by Scott (dS)
d = dK + dS
We know that the formula for distance is:
distance = velocity * time
So,
d = vK * t + vS * t
where
vK = velocity of Krystal = 61 mph
vS = velocity of Scott = 65 mph
d = 252 miles
Therefore:
252 = 61 t + 65 t
126 t = 252
t = 2 hours
Therefore Scott needs to travel for 2 hours.
Answer:
14
Step-by-step explanation:
its an formula which comes in algebraic expression
Answer:
I am not sure but I think its 42 reason is multiplication I might be wrong if its an exam or test or quiz dont use this answer
Step-by-step explanation:
One company charges:
$376 + $12*h
Other company charges:
$280 + $15*h
They will both charge the same when:
$376 + $12*h = $280 + $15*h
96 = 3*h
hours = 32
Cost will be $760
Double Check
$376 + $12 * 32 hours = $760
$280 + $15 * 32 hours = $760
