The fuel consumption of a certain car is 24 miles per gallon. How many Kilometers per liter is this? I know that 1 mile = 1.61 k
Mariulka [41]
I'm pretty sure its 38.6 km to every 3.78 liters. and then after that you simply need to divide properly to reduce to show the amount for 1 liter of gas exactly.

Emma runs 3/4 mile in 6 minutes . Joanie runs 1 1/2 mmiles in 11 minutes. Whose speed is greater? Explain
cupoosta [38]

1) with the formula  V=X/T, where X is distance and T is time you can verify with speed is greater

the speed of Emma is V = 3/4÷6 , V = 3/4 × 1/6 = 3/24 ⇒V = 1/8 m/h

the distance of joanie is 1 + 1/2 = 3/2 now the speed of Joanie is V= (3/2) ÷11 , V = (3/2)÷11 , V = 3/22 m/h

as 1/8 = 0.125 and 3/22 = 0.136 then the speed of  joannie is greater than Emma
