Answer:
5mph
Step-by-step explanation:
Given that two cars are 40 miles apart at the beginning.
They started at the same time with speeds 48 mph and 56 mph respectively
Since both cars are travelling in the same direction,
Relative velocity = Speed of the behind car-Speed of the first car
=56-48 =8mph
To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car
i.e. speed to be made up by the second car = 40 miles
Relative velocity per hour = 8mph
Hence time taken to catch up =
Length squared + width squared = Diagonal squared
Length squared = 900cm
Width squared = 256cm
total = 1156
Therefore Diagonal squared = 1156
Diagonal = 34cm
Length squared = 900cm
Width squared = 256cm
total = 1156
Therefore Diagonal squared = 1156
Diagonal = 34cm
