Coordinates of Q is (0, –8) and point P lies on the x-axis and the right side of y-axis. Given that the distance between PQ is 10 units, find the gradient of PQ.

step-by-step explanation:

compare

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
