Answer:
Rate = 108 km/hr
Distance travelled in 2 hours = 216 km
Step-by-step explanation:
A car is travelling at a rate of 30 meters per second
1 km = 1000 meters
? km = 30 meters
Cross multiplying gives; km
1 hr = 3600 seconds
? hrs = 1 second
Cross multiplying gives; hrs
Speed = Distance ÷ Time
Speed in km/hr = km ÷ hrs = km × = 108 km/hr
Distance travelled in 2 hours = 2 × 108 km = 216 km
Answer:
16.93 cm to the nearest hundredth.
Step-by-step explanation:
Volume of the metal sphere = 4/3 π r^3
= 4/3 * π * 10.5^3
= 4849.048 cm^3.
This will be the volume of the cube made.
The volume of a cube = L^3 where L = length of one side.
So L^3 = 4849.048
L = ∛(4849.048)
L = 16.926 cm.
