Students often get stuck before they start this kind of problem because they don't remember the formulas. Think of a speed limit sign ; it says "speed = miles per hour", which tells you that rate equals distance divided by time. There is a nice trick of writing the letters D, R and T in a triangle to find the other two formulas, but I can't show it without making a drawing. You can also find the other two formulas by algebra. The 3 formulas are D=RT, R=D/T and T=D/R.
T=D/R; D=150 and R=60
T = 150/60 = 2.5 hours, or 2 hours and 30 minutes.
That depends on your speed.
It would depend on your speed
73 / A = hours of travel time
That depends on your speed.
That depends on your speed.
long would it take to go 6600 miles by train?
The speed of light is ~186,282 Miles per second. You do the math.
Time = Distance/Speed
You would need to know the speed.
That depends on the speed. Choose a suitable speed, then divide the distance by the speed.
It would depend on the car's speed.
It depends on the speed of the ship.
