I need help with these 3 question I don't understand how to solved it.
1)If a marathon race is 28.2 miles. What us the distance in kilometers? (1mile=1.61 kilometers)
2) If Earth is 93,000,000 miles from the sun. What is the distance in kilometers? (1 kilometers=0.619 miles)
3) The energy value of protein is 4.0cal/g. Calculate the energy in 250g of protein and Express the value in joules (J) (1cal=4.184J)
Expert Solution
Basic
The some Basis conversion are ;
1mile=1.61 kilometres
1 kilometres=0.619 miles
1cal=4.184J
Energy value of protein = 4.0cal/g
By using all this we can solve the above problem .
