Answer:
The speed is 60 mph.
Step-by-step explanation:
distance = 42 miles
Let he drove with speed v and time is t.
distance = speed x time
42 = v t ..... (1)
42 = (v + 10)(t - 1/10) ..... (2)
So, the speed cannot be negative so the speed is 60 mph.
Answer: y= 64
Step-by-step explanation:
If y is 16 when x is 2 This means if x is 8 y will be 64.
Set up the proportional equation
Cross multiply
2y = 128
y= 64
The final loss percent is 0.25%.
<h3>What is the final loss percent?</h3>The gap between the cost price and the selling price is what is referred to as a loss. And the loss percent is the loss as a percentage of the actual cost.
Total CP=Rs. 400
Let the CP of the first watch be Rs. x
So, CP of the second watch=Rs.(400-x)
For the first watch,
Gain Percent=5%
SP =
SP=105x/100
For the second watch,
Loss Percent=5%
SP=
SP=95(400-x)/100
As the SP of both the watches is the same.
105x=38000-95x
105x+95x=38000
200x=38000
x=38000/200
x=190
CP of the first watch=Rs. 190
CP of the second watch=Rs. (400-190)=Rs. 210
SP of first watch= =Rs. 199.50
SP of second watch==Rs. 199.50
Total SP=Rs. 399
Final Loss=Total CP-Total SP
=Rs.(400-399)
=Rs. 1
Final Loss Percent=100/400
=0.25%
