If the runner moves at 6 miles per hour for 2 hours before the cyclist starts, the runner has a 12 mile lead at the beginning. If the cyclist is going at 16 miles per hour, he is overtaking the runner at 10 miles per hour, because 16-6=10. Then, the amount of time it takes the cyclist to go 2 miles in 10 miles per hour is the answer. this is 1/5 of an hour, or 12 minutes.
Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml
