Step-by-step explanation:
Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
The above question is solved using Proportion method
2.5 hours = 56 mph
2 hours = x mph
Cross Multiply
2.5 hours × x mph = 2 hours × 56 mph
x mph = 2 hours × 56 mph/2.5 hours
x mph = 44.8 mph
Therefore, Mac's average speed = 44.8 mph

Answer:
40 2/5Ibs or
lbs
Step-by-step explanation:
Let weight of object on the moon be represented = Wm
weight of object on the Earth = We
In the above question, we are told:
The weight of an object on the moon is
5 of its weight on Earth.
Hence, mathematically, this is represented as:
5Wm = We
If a moon rock weighs 202 lbs on Earth
5Wm = 202lbs
Wm = 202lbs/5
Wm =
Ibs
Therefore, the moon rock weighs
Ibs on the moon.
