The speed is defined as the ratio between the distance you cover and the time it takes you to cover that distance.

So, in this case, we have

s = \dfrac{3.5}{0.5} = \dfrac{28}{4} = \dfrac{56}{8} = 7\text{ mph}

to find james’ constant rate of speed, you can divide miles by hours (m/h)

28 miles / 4 hours = 7

56 miles / 8 hours = 7

3.5 is half of 7, so we know that’s true as well

this means james’ constant rate of speed would be 7 mph

By selling a watch in Rs 150 and Rs 200 loss and profit are happened
Travka [436]

Answer:

Rs 175

Step-by-step explanation:

Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).

At Rs200, the profit is 200-x.

So we have an equation: minus 150 minus x is equal to 200 minus x.

To solve the equation, the cost price X is Rs175.
