You would use the equation
F+V=E+2
<span>120 miles----------------------1 hour.
45 miles ----------------------?? x hours
x= 45 / 120 = 0.375 hours

Distribute to every term inside the parentheses.
Simplify with multiplication.
You can't simplify further by adding, so leave the answer as-is.
Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be ,
Speed uphill is . We are told than speed uphill is the speed on flat ground. Therefore the speed on level ground will be .
From this info, we can obtain the actual speed, on level ground as:
speed, distance and time have the relation so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.
Answer:
56.7 mi/h
Step-by-step explanation:
The formula for average speed is:
Average Speed =
Thus we have:
Average Speed = mph
<em>Rounding to the nearest tenth, we have </em>
Average Speed = 56.7 mi/h
