Can someone me with these four problems, show work plzz

1. d = rt You must isolate r, so divide by t and you get r = d/t

2. Average speed is the total distance divided by the total time. 400m/43.83s=9.1m/s (Round to the nearest tenth, says in question)

3. Same thing but with Garcia's measurements. 110m/13s=8.5m/s (Round to the nearest tenth, says in question)

4. Kenteris's Speed = 200m/20.09s=9.9552m/s (Do not round until final answer) Johnson's Speed = 200m/19.32s=10.3520m/s

10.3520m/s - 9.9552m/s = .4 m/s (Round to the nearest tenth, says in question) The difference in speed is found by simply subtracting. Johnson went .4 m/s faster on on average than Kenteris.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
