The time that it takes you to drive a certain distance variesinversely as your driving rate. Averaging 40 miles per hour, ittakes you 10 hours to drive the distance. How long would thetrip take averaging 50 miles per hour?1.Time, t, varieskinversely as rate, r.t =2. It takes 10 hours at 40 miles per hour.k1040k = 10(40) = 4004003. t=4. How long at 50 miles per hour? Substitute 50 for r.400t == 850It takes 8 hours at 50 miles per hour.

We will use the formula: Distance= speed × time Given that my driving speed= 40 miles per hour.…

A radar gun recorded the speed of an arrow as it was shot off of a cliff. Here is the information… time speed 0 seconds 200 1 168 2 136 3 104 It was recorded that the speed of the arrow when it hit the ground was -210.88 feet per second. Use all of this information to determine the initial height that the arrow was shot from
When there is no wind, a runner is able to run 10 000 m at an average speed of x m/s. When he runs with a tailwind, his average speed increases by 0.05 m/s and it takes him 15 s less to run the 10 000 m. The equation shown below represents this relationship. 10 000 10 000 x+0.05 X = 15, x > 0 6. When there is no wind, find the runner's average speed, to the nearest hundredth of a metre per second.
